Abstract
The aion exchange membrane fuel cell has been attracting attention in recent years, because the inside of the cell is alkaline and an inexpensive catalyst can be used. However, it is a matter of anxiety that generated water covers the reaction surface. and the performance deteriorates, because it is necessary to humidify supplied gas in order to generate electricity using hydroxide ion. In this research, while investigating the basic performance. the influence of water generation on power generation performance was investigated. By varying the operating temperature. it turned out that the output voltage was high when the operating temperature was high. Moreover, it turned out that there was no performance deterioration by generating water. In the experiments conducted while varying the humidity of the supplied gases, it turned out that activation overpotential became low and the output voltage became high by humidifying the supplied gas more.
