Inexpensive Cathode Catalysts.
Abstract
The report is a summation of the findings and developments aimed at the development of a low cost air cathode. The purpose was to lower the cost of air breathing fuel cells having moderate (125-135C) temperature phosphoric acid as the electrolyte. A new type of particulate graphite substrate was developed to replace metal grid support structures. A 2 mg/sq cm cathode containing small amounts of graphite and supported on a graphite substrate represents a total cathode costs of $167/Kw based on performance after 500 hours of testing at 100 mA/sq cm.
