The fuel cell (1) has a cathode (C) supplied with combustive material and an anode (A) supplied with fuel (10). The combustive material (2) is carried in a transport gas. A purge circuit (5,6,7,8) delivers inert gas to the anode when the fuel cell is stopped, preventing fuel build up. The purge circuit diverts some of the transport gas away from the anode, and also separates (6) combustible material from the transport gas. |
