Abstract: A fuel cell power system includes a fuel cell stack having at least two fuel cell groups in series with each other and with each fuel cell group having more than one individual fuel cell, and a power controller which receives electrical power from the fuel cell stack and distributes the electrical power to an output bus. The power controller includes a DC-DC converter, and a reduction logic circuit operative to limit current through the DC-DC converter in response to voltage across each fuel cell group so that a minimum voltage is maintained across each fuel cell group. When used in combination with a hydrogen reformer, the reduction logic circuit is also operative to limit current through the DC-DC converter in response to hydrogen pressure supplied by the reformer to the fuel cell stack so that a minimum pressure is maintained for the hydrogen supplied to the fuel cell stack.
