HSC Chemistry Research Assignment Topic: The Production of Materials Lloyd Ruz Cell Type: Hydrogen-Oxygen Fuel Cell The structure of the cell The Hydrogen-Oxygen Fuel cell uses hydrogen as its fuel source. The basic structure of such a fuel cell is outlined below: Figure 8A The chemistry of this cell will be outlined below. The chemistry and function of the cell Two separate half-cell reactions occur to produce a flow of electrons (current): * At the Anode, Hydrogen gas is oxidised, allowing protons (H+) to enter the proton exchange membrane (or polymer electrolyte membrane, coincidentally, both mean the same thing, in this case, and have the same abbreviation: PEM) and electrons (e-) to travel around a circuit to the cathode. Hence the following oxidation reaction takes place: * At the Cathode, protons that have permeated through the membrane and oxygen molecule which has dissolved through the electrode are reduced by electrons that have completed the circuit. Hence, the following reduction reaction...
