  • FUEL CELL POWER PLANT INCLUDING A VARIABLE RESISTIVE DEVICE
    Publication number: 20100028729
    Abstract: A fuel cell power plant (20) includes a variable resistive device (30). In one example, the variable resistive device (30) is operationally associated directly with a cell stack assembly (22). The controller (32) selectively varies an electrical resistance of the variable resistive device (30) responsive to an operating condition of the power plant (20). By using a variable resistive device, a variety of control functions are possible to address various operating conditions of the power plant (20) or the cell stack assembly (22).
