Abstract
A fuel cell system includes a fuel cell stack, a battery system, a power communication line and a power conditioning circuit. The fuel cell stack provides a stack voltage that stays near or below a first maximum voltage. The battery system includes a terminal that is coupled to the power communication line. The power conditioning circuit, in response to the stack voltage, provides a second voltage to the power bus. The second voltage stays near or below a second maximum voltage, and the second maximum voltage is greater than the first maximum voltage.
