OXYGEN ELECTRODES FOR RECHARGEABLE ALKALINE FUEL-CELLS

The primary objective of this program is the investigation and development of electrocatalysts and supports for the positive electrode of moderate temperature, single-unit, rechargeable, alkaline fuel cells. Viable candidate materials must meet the following requirements: (i) good electrical conductivity (typically a more demanding requirement for supports than for electrocatalysts); (ii) high resistance to chemical corrosion and electrochemical oxidation and/or reduction; (iii) electrocatalysts, in addition, must exhibit high bifunctional electrocatalytic activity (O//2 evolution and reduction).
