Abstract
A fuel cell system that employs a split fuel cell stack, where fresh anode gas is humidified by water trap humidifiers. The fuel cell system includes a plurality of valves that are opened and closed to provide stack order switching between the split stacks so that the flow of hydrogen through the stacks is always in the same direction. A water trap humidifier is provided at the anode inlet to both split stacks, possibly in the anode inlet manifold or fuel cell non-active region, to provide the humidification. The valves are selectively opened and closed to provide fresh hydrogen to one stack, and humidified hydrogen to the other stack.
