| Outline of Final Research Achievements |
It was revealed that a sort of enzyme in Yast Extract (YE) catalyzed the glucose oxidation in the glucose-air fuel cell operated at the high temperatures. It was also clarified that YE solution contains a substance that act as a mediator. An electrode consists of carbon powder on which YE is fixed by using chitosan was developed for the fuel cell. The fuel cell generated power by supplying only a glucose solution without adding mediator and YE as fuel. A three times higher power density compared to that of the previous fuel cell using YE was obtained. Based on the glucose consumption during 24 h operation, the energy conversion efficiency was calculated to be 0.3 %.
