Abstract

An illustrative example method of controlling operation of a fuel cell power plant includes opening a pneumatic valve using pneumatic pressure of pressurized fuel cell reactant, allowing the pressurized fuel cell reactant to flow through the pneumatic valve to a cell stack assembly, determining that shutdown of the cell stack assembly is desired, and control a rate that the pneumatic valve closes by controlling a rate of release of the pneumatic pressure.
