Fuel cell with in-cell humidification

摘要

A fuel cell plate integrating an active flow field zone for carrying out electrochemical reaction and at least one humidification zone for humidifying reactant stream. The area of the humidification field is proportionally designed to the fuel cell active flow field so that an adequate humidity and temperature can be achieved for fuel cell systems that can have different capacities, under which resizing the humidifier would be otherwise required by the prior art designs.
