摘要： A method for depositing a hydrophilic and electrically conductive layer onto a bipolar plate substrate for a fuel cell in a one step process. The method includes mixing a solution of a conductive material, such as gold particles, and a hydrophilic material, such as silicon dioxide particles, in a suitable solvent, such as ethanol. The solution is then deposited on the bipolar plate substrate by any suitable low cost process. Once the solution dries and the ethanol has evaporated, a thin layer of the conductive and hydrophilic particles remains on the substrate. In one embodiment, the conductive particles are significantly larger than the hydrophilic particles to provide both the desirable hydrophilicity and the low contact resistance.
