Single chamber fuel cathode materials

In conventional fuel cell designs, the electrolyte not only mediates the electrochemical reactions taking place at the anode and cathode, but also separates the fuel from the oxidant to prevent direct combustion. It was already recognized by Gool [235] that (i) many fuels do not directly react with oxygen at typical fuel cell temperatures and (ii) the catalytic activity of anode and cathode materials are quite selective to certain type of reactions. This renders possible single chamber fuel cells, that is, fuel cells without separation of anode and cathode compartment (sometimes called mixed gas fuel cells). Anode and cathode may then be placed either on the two sides of the electrolyte like in...
