Abstract
A method for manufacturing a functionalized metal oxide product configured to be used in an anode catalyst layer of a fuel cell can include forming a catalyst solution, which can include mixing a metal oxide in water. A stock solution can be formed by mixing a fatty acid in water. The stock solution can be added to the catalyst solution to form a solid fraction and a liquid fraction. The solid fraction can be removed from the liquid fraction. The solid fraction can be washed and dried, thereby forming the functionalized metal oxide product. The functionalized metal oxide product is configured to improve the cell reversal tolerance of the fuel cell.
