Abstract
An illustrative example method of making a fuel cell component includes mixing a catalyst material with a hydrophobic binder in a solvent to establish a liquid mixture having at least some coagulation of the catalyst material and the hydrophobic binder. The liquid mixture is applied to at least one side of a porous gas diffusion layer. At least some of the solvent of the applied liquid mixture is removed from the porous gas diffusion layer. The catalyst material remaining on the porous gas diffusion layer is dried under pressure.
