FUEL CELL H2 EXHAUST CONVERSION

摘要

A fuel cell system (20) having first (22) and second (40) fuel cells that each receive anode reactant (24) flows and cathode reactant (26) flows. Each of the cells (22, 40) uses the reactant flows to produce electricity. The electricity production by the fuel cells (22, 40) produces respective first and second anode and cathode effluents (30, 32) that are exhausted from the respective fuel cells. The second fuel cell (40) is connected to and downstream from the first fuel (22) cell so that the anode reactant (24) flow to the second fuel cell (40) is formed from a portion of the anode effluent (30) exhausted from the first fuel cell (22).
