Durable layer structure and method for making same |
| abstract |
A bipolar plate for a fuel cell that includes a hydrophilic layer deposited on the bipolar plate to a suitable thickness to satisfy hydrofluoric acid etching for the desired lifetime of the fuel cell. In one embodiment, the hydrophilic layer is a relatively thick silicon dioxide layer that is deposited on the bipolar plate as a colloidal dispersion of silicon dioxide nano-particles in a solvent. The dispersion is dried so that the solvent evaporates to form a film of the silicon dioxide nano-particles on the bipolar plate. A relatively thin layer, generally a metal oxide, is first deposited on the bipolar plate by a CVD or PVD process so that the thin layer has suitable bonding to the bipolar plate. The thicker hydrophilic layer is then deposited on the thin layer, where the bonds between the thick layer and the thin layer are suitable for the fuel cell environment. |
