Exhaust gas processing device for fuel cell

An exhaust gas processing device for a fuel cell, in which the fuel cell is supplied with air and hydrogen gas to generate electric power and the hydrogen gas discharged from an anode of the fuel cell is recirculated in a hydrogen recirculation piping system, comprising:

• a reservoir in which hydrogen gas purged from the hydrogen recirculation piping system is retained;
• a cathode exhaust gas pipe that is connected to a cathode of the fuel cell and provided with holes through which the hydrogen gas retained in the reservoir is sucked in so that the hydrogen gas is diluted with cathode exhaust gas and released into atmosphere;
• and
• a blower that supplies air to the cathode of the fuel cell and forces the air discharged from the cathode of the fuel cell to flow through the cathode exhaust gas pipe,
• wherein the hydrogen gas retained in the reservoir is diluted and released into the atmosphere even after generation of electric power in the fuel cell is stopped.
