Fuel Cell Electrodes for Hydrogen-Air Fuel Cell Assemblies

摘要

The report describes the design and evaluation of a hydrogen-air fuel cell module for use in a portable hydrid fuel cell-battery system. The fuel cell module consists of a stack of 20 single assemblies. Each assembly contains 2 electrically independent cells with a common electrolyte compartment. When supplied with hydrogen, as generated from Sodium Aluminum Hydroxide, the module is capable of delivering in excess of 60 watts at a nominal output of 15 volts. Dry weight of the module assembly is 4.2 pounds. Electrolyte reservoir capacity is 250 cc, utilizing 3 to 6 molar potassium hydroxide. (Author)
