摘要： The present invention provides an electrically conductive element for a proton exchange membrane fuel cell having low electrical contact resistance and high corrosion resistance. The conductive element comprises a corrosion susceptible metal substrate with a surface, which is preferably treated to activate the surface (i.e. to remove a passivation layer of oxides from the surface) with an acidic treatment solution. The treated surface is then overlaid with an electrically conductive, corrosion-resistant, protective coating to protect the substrate re-forming a passivation layer while exposed to the corrosive environment of the fuel cell. The present invention also provides methods of preparing an electrically conductive element to have low electrical contact resistance and high corrosion resistance.

摘要： A fuel cell system that employs a surface active agent that reduces the surface tension of the water in the flow field channels. The fuel cell system includes humidifiers that humidify the cathode inlet airflow and the hydrogen anode gas. The surface active agent is mixed with the humidifying water in the humidifiers so that the surface active agent enters the flow field channels to reduce the surface tension of the water therein, thus allowing the water to wick the channels. In one non-limiting embodiment, the surface active agent is ethanol. Ruthenium can be added to the platinum in the catalyst layers of the fuel cells to mitigate the poisoning of platinum by carbon monoxide, which is one of the oxidation products of ethanol on the cathode side of the fuel cell.
