摘要：
Fuel exhaust (109) of a primary fuel cell stack (11) flows into an auxiliary fuel cell stack (12) which powers a DC storage (82) feeding a bi-directional DC/AC converter (86) that is switchable (89) to auxiliary equipment (90, 91) (such as pumps) to a main power bus (54) feeding a main load (55). Fresh fuel (97) is provided (98, 105) to the primary stack for 90% fuel utilization, with over 99% overall power plant fuel utilization. The auxiliary equipment (90, 91) may be powered by the bus (54).
