SOLID ALKALINE FUEL CELL

The solid alkaline fuel cell has a cathode that is supplied with an oxidant which contains oxygen, an anode that is supplied with a fuel which contains hydrogen atoms, and an inorganic solid electrolyte that is disposed between the anode and the cathode and that exhibits hydroxide ion conductivity. The inorganic solid electrolyte enables permeation of a fuel in an amount that produces carbon dioxide at the cathode of greater than or equal to 0.04 μmol/s·cmand less than or equal to 2.5 μmol/s·cmper unit surface area of a cathode-side surface.
