Abstract
A membrane electrode assembly for a fuel cell has a segmented membrane including a porous support having a surface area, the surface area divided into a first portion and a second portion. An alkaline segment is formed from the first portion of the porous support imbibed with an alkaline ionomer. An acid segment is formed from the second portion of the porous support imbibed with an acid ionomer. The alkaline segment is sized to provide a humidification amount to a feed gas passing through the acid segment.
