摘要： A method for operating a fuel cell power plant. The fuel cell can include a reactant passage (22) with an upstream portion and a downstream portion for providing reactant to an electrode (16, 18), at least one liquid passage (24), and a plate (20) made from a porous material that is liquid permeable and conductive. The porous material separates the reactant passage and the liquid passage. A pressure profile is controlled to provide a positive pressure difference in the upstream portion and a negative pressure difference in the downstream portion. A positive pressure difference is one where the liquid pressure is higher than that of the reactant. A negative pressure difference is one where the liquid pressure is less than that of the reactant. The pressure profile can be used to provide enhanced humidification of the reactant in the upstream portion and effective liquid water removal in the downstream portion to maximize both the performance and the life of the fuel cell.

The water supply means has a water supply grooves (15) for introducing water from a water supply manifold (14) disposed on the second surface, communication holes (16) for communication of the second surface with the first surface, and a buffer section (17) having a porous body (20) for uniformly distributing water from the water supply grooves (15) to the communication holes (16). The porous body (20) extends along the second surface. The water flows in the porous body (20) along the second surface. Thus, water can be supplied uniformly to the first reactant gas supply grooves (9a) of each of the reactant gas supply separators (5).

摘要： A fuel cell power system includes a fuel cell stack prepared by stacking a plurality of electric cells, each having an anode and a cathode with an electrolyte therebetween, a fuel supply line and an oxidant supply line that respectively supply a fuel and an oxidant to the fuel cell stack, and a fuel exhaust line and an oxidant exhaust line that respectively exhaust the fuel and oxidant supplied to the fuel cell stack. A method for retaining a power generation-suspended state of the fuel cell power system in a process of bringing the fuel cell power system into the power generation-suspended state and retaining the suspended state includes the steps of: closing the oxidant supply line in the course of bringing the fuel cell power system into the power generation-suspended state; applying a direct current from the cathode to the anode through an external circuit with the oxidant supply line closed by the step of closing the oxidant supply line until the electric cell voltage with reference to the anode comes to a level of more than −1.2 V to less than 0.1 V; closing the oxidant exhaust line after the start point of the step of applying a direct current; and closing the fuel exhaust line and the fuel supply line after the termination point of the step of applying a direct current.
