Abstract
An exchange membrane includes, for example, a first layer membrane having a first thickness, a second layer membrane having a thickness less than the first thickness, and the second layer membrane containing a catalyst, a catalyst content in the second layer membrane being greater than a catalyst content in the first layer membrane, and the exchange membrane having an interface between the first layer membrane and the second layer membrane. In some embodiments, the membrane electrode assembly (MEA) includes the first layer membrane without a catalyst, and/or the exchange membrane includes a bi-layer exchange membrane.
