Abstract
A fuel cell system includes at least one fuel cell module and at least one relational water seal configured to limit a magnitude of a pressure differential in the fuel cell system in an anode under-pressurization situation in which the second pressure exceeds the first pressure by at least a first predetermined amount. The fuel cell module includes a fuel cell assembly having one or more fuel cells arranged in a stack configuration, an anode inlet manifold, an anode outlet manifold having a first pressure, a cathode inlet manifold having a second pressure, and a cathode outlet manifold.
