METHOD FOR OPERATING FUEL CELL, AND ELECTRIC-POWER GENERATING DEVICE |
摘要 |
Provided is a method for operating a fuel cell involving supplying an electrode with a low or non-humidified gas that achieves no significant decrease of voltage as compared with when a high-humidified feed gas is used. The method for operating a fuel cell having a membrane electrode assembly includes a cathode, an anode and an electrolyte membrane interposed between both the electrodes, wherein the cathode has a layer including an oxygen reducing catalyst including composite particles which include atoms of a metal element M1, carbon, nitrogen and oxygen and in which primary particles of a compound of the metal element M1 are dispersed in a carbon structure, which method includes supplying the cathode with an oxidizing agent gas which includes an oxygen gas and which has a relative humidity at a temperature of the membrane electrode assembly of 60% or less, and supplying the anode with a fuel gas. |
