  • What Are Regenerative Fuel Cells? 1 of 8
    What Are Regenerative Fuel Cells? 1 of 8 altenergy.org What Are Regenerative Fuel Cells? Alan Davison 11-14 minutes Scientists, researchers, and engineers are on a quest for the holy grail of energy technologies, and a key component of any energy system is figuring out new and innovative ways to store energy. One of the most popular visions for a renewable energy future is the hydrogen economy, but the question as to where one gets the hydrogen required to sustain it is as old as the idea itself. The regenerative fuel cell might be the answer that hydrogen economists are looking for. What are regenerative fuel cells? Ever wonder what would happen if you could run a fuel cell in reverse? You get a reverse fuel cell (RFC) or regenerative fuel cell. If a fuel cell is a device that takes a chemical fuel and consumes it to produce electricity and a waste product, an RFC can be thought of as a device that takes that waste product and electricity to return the original chemical fuel. Indeed any fuel cell chemistry can be run in reverse, as is the nature of oxidation reduction reactions, but a fuel cell that isn't designed to do so may not be very efficient at running in reverse. In fact many fuel cells are designed to prevent the reverse reaction about:reader?url=https://www.altenergy.org/renewables/regenerative-fuel-cells.html What Are Regenerative Fuel Cells? 2 of 8 from occurring at all, for why would you want to consume the energy you just produced? Instead you might design a separate cell for the express purpose of taking energy generated from another source and storing it as a fuel for conversion back into energy when you need it via fuel cell.

  • Electrolysis in Ironmaking
    Fact sheet Electrolysis in ironmaking The transition to a low-carbon world requires a transformation in the way we manufacture iron and steel. There is no single solution to CO2-free steelmaking, and a broad portfolio of technological options is required, to be deployed alone, or in combination as local circumstances permit. This series of fact sheets describes and explores the status of a number of key technologies. What is electrolysis? Why consider electrolysis in ironmaking? Electrolysis is a technique that uses direct electric current to There are two potential ways to separate metallic iron from separate some chemical compounds into their constituent the oxygen to which it is bonded in iron ore. These are parts. through the use of chemical reductants such as hydrogen or carbon, or through the use of electro-chemical processes Electricity is applied to an anode and a cathode, which are that use electrical energy to reduce iron ore. immersed in the chemical to be electrolysed. In electrolysis, iron ore is dissolved in a solvent of silicon Electrolysis of water (H2O) produces hydrogen and oxygen, dioxide and calcium oxide at 1,600°C, and an electric current whereas electrolysis of aluminium oxide (Al2O3) produces passed through it. Negatively-charged oxygen ions migrate metallic aluminium and oxygen. to the positively charged anode, and the oxygen bubbles off. Positively-charged iron ions migrate to the negatively- charged cathode where they are reduced to elemental iron. If the electricity used is carbon-free, then iron is produced without emissions of CO2. Electrolysis of iron ore has been demonstrated at the laboratory scale, producing metallic iron and oxygen as a co-product.

  • Electrolysis of Salt Water
    ELECTROLYSIS OF SALT WATER Unit: Salinity Patterns & the Water Cycle l Grade Level: High school l Time Required: Two 45 min. periods l Content Standard: NSES Physical Science, properties and changes of properties in matter; atoms have measurable properties such as electrical charge. l Ocean Literacy Principle 1e: Most of of Earth's water (97%) is in the ocean. Seawater has unique properties: it is saline, its freezing point is slightly lower than fresh water, its density is slightly higher, its electrical conductivity is much higher, and it is slightly basic. Big Idea: Water is comprised of two elements – hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it becomes an electrolyte solution, able to conduct electricity. Key Concepts o Ionic compounds such as salt water, conduct electricity when they dissolve in water. o Ionic compounds consist of two or more ions that are held together by electrical attraction. One of the ions has a positive charge (called a "cation") and the other has a negative charge ("anion"). o Molecular compounds, such as water, are made of individual molecules that are bound together by shared electrons (i.e., covalent bonds). o Essential Questions o What happens to salt when it is dissolved in water? o What are electrolytes? o How can we determine the volume of dissolved ions in a water sample? o How are atoms held together in an element? Knowledge and Skills o Conduct an experiment to see that water can be split into its constituent ions through the process of electrolysis.

High-energy Hydrogen I Teacher Page Electrolysis of Water Student Objective The student: Key Words: • will be able to explain how hydrogen compound can be extracted from water electrolysis • will be able to explain how energy hydrogen flows through the electrolysis system molecule oxygen Materials: • photovoltaic cell (3V min) or 9-volt Time: battery (1 per group) 1 hour • piece of aluminum foil, approx. 6 cm x 10 cm (2 per group) • salt • electrical wires with alligator clips (2 per group) • beaker or small bowl (1 per group) • water • stirring rod or spoon • graduated cylinder (several per class) • Science Journal Background Information When you add salt to the water, the salt ions (which are highly polar) help pull the water molecules apart into ions. Each part of the water molecule (H2 O) has a charge. The OH- ion is negative, and the H+ ion is positive. This solution in water forms an electrolyte, allowing current to flow when a voltage is applied. The H+ ions, called cations, move toward the cathode (negative electrode), and the OH- ions, called anions, move toward the anode (positive electrode). Bubbles of oxygen gas (O2 ) form at the anode, and bubbles of hydrogen gas (H2 ) form at the cathode. The bubbles are easily seen.

One of methods to produce hydrogen is by electrolysis of water. Variables that was applied in this work were electrical current (0.5 A and 0.9 A), pH (13.47 and 13.69), and electrolyte additions (namely NaOH and KOH) with processing times for 30 minutes. The result of this work were variations of electrical current at 0.9 A, pH at 13.69 and electrolyte NaOH is at 278.394 L with volume rate 154.663 mL/s produced most amount of hydrogen, whereas condition of 0.5 A, pH 13.47 and electrolyte KOH was 75.122 L with volume rate of 41.734 mL/s yielded the lowest amount.

  • Petri Dish Electrolysis Electrolysis Reactions SCIENTIFIC
    Petri Dish Electrolysis Electrolysis Reactions SCIENTIFIC Introduction Electrolysis is defined as the decomposition of a substance by means of an electric current. When an electric current is passed through an aqueous solution containing an electrolyte, the water molecules decompose via an oxidation–reduction reaction. Oxygen gas is generated at the anode, hydrogen gas at the cathode. Depending on the nature of the electrolyte, different reactions may take place at the anode and the cathode during the electrolysis of aqueous solutions. Build simple and inexpensive electrochemical cells using Petri dishes to compare the reactions of sodium sulfate, potassium iodide, and tin(II) chloride. Concepts • Electrolysis • Oxidation and reduction • Anode and cathode • Acid–base indicators Materials Phenolphthalein indicator solution, 0.5%, 1 mL Beral-type pipets, 2 Potassium iodide solution, KI, 0.5 M, 20 mL Paper clips, 2 Sodium sulfate solution, Na2SO4, 0.5 M, 20 mL Paper towels Starch solution, 0.5%, 1 mL Pencil leads, 7 mm, 2 Tin(II) chloride solution, acidified, SnCl2, 1 M, 20 mL* Petri dish Universal indicator solution, 5 mL Stirring rod 9-V Battery Wash bottle and distilled water Battery cap w/ alligator clip leads *See the Preparation section. Safety Precautions The acidic tin(II) chloride solution is corrosive to body tissue and moderately toxic by ingestion. Phenolphthalein and universal indicators solutions contain ethyl alcohol and are flammable liquids. Keep away from flames and heat. Avoid contact of all chemicals with eyes and skin. Wear chemical splash goggles, chemical-resistant gloves, and a chemical-resistant apron. Wash hands thoroughly with soap and water before leaving the lab.
