An electrolyte membrane comprising a reinforcement structure and an ionomer is provided. The reinforcement structure comprises a plurality of pores with a diameter of 0.3 mum to 2.5 mum as established by a PMI Capillary Flow Porometer and exhibit a linear swelling expansion below 0.5% for all directions in the X-Y plane. Furthermore, a method of manufacturing such electrolyte membranes is provided. The electrolyte membrane is particularly suitable for application as electrolyte membrane in low temperature fuel cells, such as polymer exchange fuel cells and direct methanol fuel cells, and in electrolysis cells. |
