PURPOSE:To increase the life of a fuel cell by supplying cathode and anode reactants into a cathode and an anode respectively after allowing them to pass through the saturate solution of a salt, and making them to react through a heteropoly acids solid electrolyte. CONSTITUTION:An anode reactant such as hydrogen gas is supplied from A, and a cathode reactant such as oxygen gas is from B, regulated in their humidity through humidity adjusting units C and D, and then supplied into an anode 14 and a cathode 15 of a fuel cell E respectively. Humidity adjusting units C and D contain the saturated solution of a salt such as KNO2, KCNS, NaNO2, through which the humidity of reacting gases is adjusted to a constant level. Hydrogen gas and oxygen gas supplied into the anode 14 and cathode 15 from a hydrogen supply pipe 11 and oxygen supply pipe 12 respectively shall react electrochemically through heteropoly acid solid electrolyte 13 such as 18-hydrate of 12- molybdophosphoric acid, 20-hydrate of 12-tungstophosphoric acid. |
