Abstract
An automated reactant flow control subsystem is provided for a fuel cell system. The subsystem is achieved with a minimum of parts for decreased cost and increased reliability. The subsystem includes a fail-safe solenoid-actuated three-way valve in the fuel line that achieves very low pressure drop and very low parasitic load requirements. The subsystem also includes a fuel bypass system such as a flare, and a controller to automatically interlock the fuel and oxidant streams of the fuel cell.
