摘要: A passive humidifier membrane includes polyolefin with a plurality of pores, wherein the average pore size of the plurality of pores is 0.05 μm to 0.4 μm as established by a PMI Capillary Flow Porometer. The humidifier membrane is virtually airtight while providing a high transfer rate of water. Transfer of heat is also high. The humidifier membrane is particularly suitable for heat exchange and water transfer between fluids and, it is particularly useful for applications inside or outside fuel cells such as PEMFC. The membrane is also particularly useful in the application as humidifier for air or oxygen.

摘要: 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 μm to 2.5 μm 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.
