Abstract
According to one embodiment of the invention, an intermediate binding layer and a metal layer can be deposited on a silicon electrode that has been configured with a flow field for a fuel cell. The metal provides high conductivity for the electrode and can also prevent degradation of the silicon. The intermediate binding layer allows the metal to be coupled with the silicon. As one example, tantalum can be used as the intermediate layer and gold can be used as the covering layer.
