<P>PROBLEM TO BE SOLVED: To reduce the size of the entire system and optimally collect water from both an anode and a cathode. <P>SOLUTION: A fuel cell system comprises: anode off-gas discharge flow paths a3, a4, a7, and a8 through which anode off-gas discharged from a fuel cell stack 12 flows; an expander turbine 40 which absorbs pressure of cathode off-gas discharged from the fuel cell stack 12; a dilution device 32 which is disposed on the downstream side of the expander turbine 40 and into which the anode off-gas is introduced; a second gas-liquid separator 42 which collects condensed water from the dilution device 32; and a water injection mechanism 44 which injects water collected by the second gas-liquid separator 42 towards inside of a pipe b1 into which air is introduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
