    摘要： The present invention provides a method of preparing a catalyst material, said catalyst material comprising a support material and an electrocatalyst dispersed on the support material; said method comprising the steps: i) providing a support material; then ii) 10 depositing a silicon oxide precursor on the support material; then iii) carrying out a heat treatment step to convert the silicon oxide precursor to silicon oxide; then iv) depositing said electrocatalyst or a precursor of said electrocatalyst on the support material; then v) removal of at least some of the silicon oxide.

    摘要： The present invention concerns a method for preparing a catalyst coated membrane including the steps of: coating a substrate with a first catalyst dispersion thereby obtaining a first catalyst dispersion coated substrate, providing a second side of a membrane with a support film, coating a first side of the membrane with a second catalyst dispersion, thereby obtaining a second catalyst dispersion coated first side of the membrane, drying the first catalyst dispersion thereby obtaining a first catalyst coated substrate or drying the second catalyst dispersion coated first side of the membrane thereby obtaining a second catalyst coated first side of the membrane, laminating the first catalyst coated substrate to the second catalyst dispersion coated first side of the membrane or laminating the first catalyst dispersion coated substrate to the second catalyst coated first side of the membrane so that the first catalyst and the second catalyst superimpose, thereby forming a laminate including a membrane comprising a first catalyst layer, drying the laminate, removing the support film from the second side of the membrane, coating a third catalyst dispersion on the second side of the membrane, drying the third catalyst dispersion, thereby obtaining a second catalyst layer on the membrane, and removing the substrate from the first catalyst coated substrate.
