Abstract:
An improved fuel cell system comprising a component designed to minimize or otherwise prevent the collection of water (and thus formation of ice at low temperatures) at valves or other anode exhaust flowpath control points. Thus, such system is configured to be operable under at least freeze start conditions. Also provided, in various embodiments, are methods of controlling ice blockage in a fuel cell system by, among other things, providing such a component.
