Abstract
A power generation device, comprising a fuel, an anode and a cathode, the anode comprising an enzyme that promotes oxidation of the fuel, and the power generation device containing more water when generating power than when not generating power.
Claims20
A power generation device, comprising a fuel, an anode and a cathode,
- the anode comprising an enzyme that promotes oxidation of the fuel,
- the fuel being positioned between the anode and the cathode, and
- the power generation device satisfying at least one of the following (1), (2) or (3):
- (1) containing more water when generating power than when not generating power;
- (2) generating power by supply of a liquid;
- and
- (3) containing water in an amount of 10% by mass or less relative to a total mass of the fuel, the anode and the cathode.
