PROBLEM TO BE SOLVED: To make operability excellent, to reduce a device size and a cost, and to enhance efficiency under power generation, by producing pure water without using pressurizing means such as a compressor and without using power and by mixing the water with a fuel to be supplied to a unit cell of a fuel cell. SOLUTION: This fuel cell with plurally stacked unit cells for the fuel cell comprising a sheetlike solid polymer electrolyte film, a fuel electrode film and an oxidant electrode film joined respectively to both main faces of the electrolyte film, a separator for a fuel gas having a fuel gas passage 4 and a separator for an oxidant gas having an oxidant gas passage respectively in both outside faces thereof has a high pressure cylinder containing high pressure hydrogen or a hydrogen storage alloy tank 22, and a water container 11 storing water to be purified, the water is passed through a porous film 15 from the water container 11 to purify the water, and resulting pure water is supplied to the fuel gas passage 4 together with hydrogen. |
