Summary: | A method of operating a phosphoric acid fuel cell (40) is provided, in which the phosphoric acid fuel cell (40) effects power generation at a high output. A power-generating cell (10) is provided with an electrolyte layer (16) comprising a matrix composed of basic polymer impregnated with acidic liquid electrolyte such as phosphoric acid. The phosphoric acid fuel cell (40) has a fuel cell stack comprising a single unit of the power-generating cell (10) or a predetermined number of the power-generating cells (10) electrically connected in series to one another. When the phosphoric acid fuel cell (40) is operated, the supply pressures of the oxygen-containing gas and the hydrogen-containing gas are set so that the pressure on a cathode electrode (14) of the power-generating cell (10) is higher than that of an anode electrode (12). |
