摘要:
Hydrogen gas supplied to and then purged from a fuel cell is temporarily retained in a reservoir provided in an exhaust fuel diluter, and diluted before release into atmosphere. Cathode exhaust gas discharged from a cathode of the fuel cell is mixed to dilute the hydrogen gas, and air continues to be supplied to the cathode of the fuel cell for a specific period of time even after generation of electric power in the fuel cell is stopped, so that the hydrogen gas retained in the reservoir is continuously diluted with the cathode exhaust gas and released. Air for ventilation of the fuel cell may be used instead or in addition, to dilute and release the hydrogen gas retained in the reservoir after the generation of electric power in the fuel cell is stopped.

An apparatus for dilution of discharged fuel of a fuel cell is provided, which has an inlet for guiding purged hydrogen gas coming from the fuel cell, a reservoir for storing the purged hydrogen gas guided through the inlet, and a cathode exhaust gas pipe penetrating the reservoir. The cathode exhaust gas pipe has a feature that it has holes inside the reservoir and is supplied with cathode exhaust gas of the fuel cell. Also the apparatus has a feature that the cathode exhaust gas pipe sucks the purged hydrogen gas stored in the reservoir through the holes and discharges the purged hydrogen gas diluted by mixing with the cathode exhaust gas.

An apparatus for cooling a fuel cell, which generates power by supplying air and a fuel gas, in which a cooling liquid is circulated between the fuel cell and a heat exchanger is disclosed. The cooling apparatus of the present invention separates the gas introduced into the cooling liquid, mixes the separated gas with the air supplied to or exhausted from the fuel cell, and then exhausts the gas.
