    Abstract: 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.

    Abstract: A fuel cell is operated with high power such that which a humidified gas and a dry gas are selectively supplied as oxidant to a cathode of the fuel cell. This method includes (S1) supplying a humidified gas while a power is constantly maintained or until the power begins to decrease; (S2) after supplying the humidified gas, supplying a dry gas to obtain a greater power than an average power of the step (S1); and (S3) after obtaining a predetermined power in the step (S2), repeatedly supplying a humidified gas in case the power decreases and supplying a dry gas in case the power decreases again afterwards, thereby increasing the power such that the predetermined power is maintained. This method provides an optimal operating condition to a fuel cell, thereby ensuring a high power.
