Abstract
A method for depositing a hydrophilic coating on flow field plates or bipolar plates and manifolds in a fuel cell stack after the stack is assembled. The method includes preparing a solution that contains hydrophilic nano-particles suspended in a suitable solvent. The cathode and anode inlet and outlet manifolds and the cathode and anode flow channels are filled with the solution. The solution is then pumped out of the stack using, for example, a stream of nitrogen. The stack is allowed to dry, using heat if desirable, to provide a film of the nano-particles formed on the anode and cathode flow channels and manifolds within the stack.
