Patent ID: 6989209

Claim:
A power generation method comprising: supplying an oxidant flow to an inlet of a fuel cell module, the fuel cell module comprising at least one fuel cell stack, the fuel cell stack including a plurality of fuel cells; supplying a fuel flow to the fuel cell module; recirculating at least thirty percent (30%) of an exhaust oxidant flow from an outlet of the fuel cell module to the inlet of the fuel cell module as a recirculated exhaust flow; blowing the recirculated exhaust flow at a blowing ratio BR; combining the recirculated exhaust flow with a new oxidant flow to form the oxidant flow supplied to the inlet of the fuel cell module; and exhausting a remaining portion of the exhaust oxidant flow from the outlet, wherein said supplying of the oxidant and fuel flows and said recirculation of at least thirty percent (30%) of the exhaust flow are controlled to achieve an equivalence ratio of at least 0.3.
