Patent number: 11502308Abstract: A catalyst-coated membrane (CCM) for use in a water electrolyser, having a laminate structure comprising: a first layer comprising a first membrane component having a cathode catalyst layer disposed on a first face thereof; a second layer comprising a second membrane component having an anode catalyst layer disposed on a first face thereof; and an intermediate layer disposed between the first and second layers, comprising a third membrane component having a recombination catalyst layer disposed on a first face thereof is disclosed. The CCM is useful within a water electrolyser. The recombination catalyst layer reduces the risk associated with hydrogen crossover and allows thinner membranes with lower resistance to be used.Type: GrantFiled: December 18, 2017Date of Patent: November 15, 2022Assignee: Johnson Matthey Hydrogen Technologies LimitedInventors: Emily Rose Price, Edward Anthony Wright
