Abstract
A fuel cell is provided that includes a water transport plate separating an air flow field and a water flow field. The driving force for moving water across the water transport plate into the water flow field is produced by a differential pressure across a restriction. The restriction is arranged between an air outlet of the cathode water transport plate and a head of a reservoir that is in fluid communication with the water flow field.
