Fuel cell and enzyme electrode
First Claim
1. A fuel cell comprising:
- a cathode;
an anode disposed opposite to the cathode; and
a proton conductor sandwiched between the anode and the cathode,wherein each of the anode and the cathode comprises;
an electrode substrate;
an enzyme fixing film for fixedly providing an enzyme to the electrode substrate; and
a current collector provided with a convex portion higher than a thickness of the enzyme film, wherein the current collector comes in contact with the electrode substrate by the convex portion.

Abstract
Provided is a fuel cell that is high in performance capabilities of initial power generation and in volume power density, and produces a stable power. Between fixing plates, first and second cell portions are provided. The first cell portion includes an anode, a cathode, and a proton conductor, and the second cell portion includes an anode, a cathode, and a proton conductor. To a space formed by gas-liquid separation and permeable films, cathode spacers, and an anode spacer, a fuel solution is filled. The gas-liquid separation and permeable films are disposed between the fixing plate and the cathode, and between the fixing plate and the cathode. The cathode spacers are provided around the cathodes, respectively, and the anode spacer is provided between the anodes.
