Abstract
A system has a fuel cell with an anode, a membrane, and a cathode. A source of fuel passes along the anode and a source of an oxygen containing gas passes along the cathode. A downstream line captures fuel downstream of the anode and a separator separates impurities from the fuel on the downstream line, and recirculates fuel downstream of the separator for passage across the anode. A method of mixing air with an oxygen concentrated gas is also disclosed.
