Abstract
An electrochemical apparatus (10) is made having a generator section (22) containing electrochemical cells (16), a fresh gaseous feed fuel inlet (28), a gaseous feed oxidant inlet (30), gaseous spent fuel recirculation channels (46), and hot combusted exhaust gas exit channels (45), where the spent fuel recirculation channel (46) passes from the generator chamber (22) to combine with the fresh feed fuel inlet (28) at a circulation and mixing apparatus (50), where a reformable fuel mixture channel (51) passes between the mixing apparatus and reforming chamber (54) containing a reformable material, where a portion of the hot combusted exhaust gas exit channel (45) surrounds the reforming chamber (54), and where the fresh feed fuel inlet has a by-pass channel (62) into the gaseous spent fuel recirculation channel (46), said by-pass channel having valving to control fresh fuel feed flow to the gaseous spent fuel recirculation channel.
