Abstract

A fuel cell which causes electrochemical ratio of conventional with oxygen consists of mainly there parts, such as electrolyte, fuel and oxidant electrode. IN this paper, most efforts were delivered to manufacturing PETE-bonded gas-diffusion electrode, and preparation methods of the porous electrodes has been discussd. A medio temperature, phosphoric acid fuel cell (PAFC) provided with fuel (hydrogen) and oxygen showed oxygen showed excellent performance characteristics with made electrodes. Performance data obtained from hydrgen-oxygen cell were presented to illustrate their properties. It was found that the optimum amounts of platinum in clectrode for hydrgen-oxygen PAFC were about 3mg/cm3 and the PTFE content of gas diffusion layer and catalyst layer were 25% and 15%, respectively.
