Abstract
IN fuel cells with an intermediate redox cycle, electrochemical reactants are prepared by the action of a fuel and an oxidant on a redox system. Complexes of copper in certain organic solvents present particularly interesting systems. For example, cupric acetate dissolved in pyridine oxidizes molecular hydrogen; cuprous acetate is the homogeneous catalyst as well as the reaction product1,2. In air, the reverse reaction proceeds with ease. Such systems may be useful in fuel cells operating on air and hydrogen as they would avoid the troublesome problem of maintaining the gas/electrolyte boundary in a specific position in the porous electrodes.
