System for the humidification of polymer electrolyte membrane fuel cells

摘要

A system for the humidification of polymer electrolyte membrane fuel cells, the system comprising a first layer and a second layer; wherein the first layer comprises a porous material (2) substantially coincident with a first surface of a polymer electrolyte membrane fuel cell (1); wherein the second layer comprises a non-absorbent material (3) substantially coincident with the first layer; and wherein perforations (4) in the second layer allow air to flow through the first and second layers to a cathode of the polymer electrolyte fuel cell.
