Abstract

A novel proton conducting polymer membrane comprising a series of channels and/or capillaries (2) for use in MEAs and fuel cells is provided. Such a membrane allows a supply of water from an external source to be supplied to said membrane allowing water electrolysis to be maintained during incidences of cell reversal in an MEA or fuel cell comprising said membrane. Methods for the construction of such a membrane are also provided.
