摘要： Moisture caused by humidity in the fuel gas and water vapor from the water that is generated become condensed inside a fuel cell when power generation in the fuel cell is temporarily stopped, making obstruction to the fuel gas flow channel when power generation is restarted possible. A fuel cell includes an electrolyte membrane sandwiched between a fuel electrode and an oxidant electrode. Oxidant is supplied to the oxidant electrode in the fuel cell, and the fuel emitted from the fuel electrode of the fuel cell is resupplied back to the fuel electrode. When requested power generating capacity for the fuel cell is less than a prescribed capacity, the oxidant supply is temporarily stopped while the fuel continues to circulate in order to prevent obstruction in the fuel flow channel due to water condensation, making a reliable fuel supply becomes possible.

摘要： Moisture caused by humidity in the fuel gas and water vapor from the water that is generated become condensed inside of the fuel cell when power generation in the fuel cell is temporarily stopped, making it necessary to prevent obstruction to the fuel gas flow channel when power generation is restarted. A fuel cell is configured so that it overlaps with a single cell comprised of an electrolyte membrane sandwiched between a fuel electrode and an oxidant electrode. Oxidant supply means 202 supplies oxidant to the oxidant electrode in the fuel cell. Exhaust fuel circulation means 205 resupplies the fuel emitted from the fuel electrode of the fuel cell back to the fuel electrode. When requested power generating capacity 201 for the fuel cell is less than the prescribed power generation capacity, oxidant supply means 202 temporarily stops the oxidant supply, while exhaust fuel circulation means 205 continues to operate and circulate the fuel, in order to prevent obstruction in the fuel flow channel due to water condensation caused by humidity or water vapor so that when the temporary stop is released and the system is restarted, a reliable fuel supply becomes possible.

摘要： A fuel cell system has a purge valve that adjusts the amount of nitrogen in a hydrogen circulation channel and a fuel electrode to be discharged through a discharge channel. A purge rate correcting unit variably sets a target control value of the nitrogen content in the hydrogen circulation channel and the fuel electrode by taking into account whether a driving mode is set in a normal power generation mode or an idle mode. An opening of the purge valve is controlled on the basis of the target control value.
