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.
