Metal coated polymer electrolyte membrane having a reinforcement structure

摘要

A metal-coated, wire-reinforced polymer electrolyte membrane that is permeable only to protons and hydrogen is disclosed. The metal-coated, wire-reinforced polymer electrolyte membrane has a surface microsturcture that prevents cracking of the metal coating during hydration. The metal-coated, wire-reinforced polymer electrolyte membrane can be used in liquid-type fuel cells to prevent crossover of fuel, gas and impurities.
