Abstract
A fuel cell system including a fuel cell stack, separator and a scavenging reservoir. The fuel cell stack is configured to generate water and reusable fuel. The separator is downstream of and in fluid communication with the fuel cell stack. The separator is configured to separate the water from the reusable fuel. The scavenging reservoir is downstream of and in fluid communication with the separator. The scavenging reservoir is configured to receive the water from the separator. The scavenging reservoir includes an inlet portion, an outlet portion, and a middle portion positioned between the inlet and outlet portions. The middle portion includes a reservoir and a passageway extending there between. The passageway is configured to allow a fluid stream to flow there through when the reservoir is occupied by a frozen fluid.
