| 摘要 |
<p>The present invention is a fuel cell power plant (10) that includes a fuel cell (12) having a membrane electrode assembly (16) which is disposed between an anode support plate (17) and a cathode support plate (19) and wherein the anode and/or cathode support plates include a hydrophilic substrate layer (80, 82) having a predetermined pore size. The pressure differential between the reactant gas streams (92, 94) and the coolant stream (96, 98) is established such that when such streams pass through the fuel cell, a greater percentage of the pores within the hydrophilic substrate layer contain reactant gas rather than water. This is controlled by creating a pressure differential between the reactant gas streams and the coolant stream such that the pressure of the reactant gas streams is greater than the pressure of the coolant stream.</p> |
