Abstract: A method for manufacturing a catalyst for a fuel cell can include provision of a platinum precursor and a carbon material. The platinum precursor and the carbon material can be mixed to form a platinum carbon mixture. The platinum carbon mixture can be heated to form a porous solid. The porous solid can be milled to form a powder. The powder can be reacted with a reducing agent to form the catalyst.

Abstract: A metallic bipolar plate has a main body coated with an overlayer. The overlayer can include a graphite-based compound. The overlayer can also include electrically conductive oxides. The electrically conductive oxides can include a member selected from a list consisting of RuIrOx (Ru rich), IrRuOx (Ir rich), RuOx, NbOx, IrOx, and combinations thereof.

Abstract: A fuel cell has an active area and a distribution area. The distribution area can be in communication with and disposed substantially adjacent to the active area. The active area can include a non-channeled material exhibiting anisotropic flow. In certain circumstances, the non-channeled material exhibiting anisotropic flow can include expanded metal sheet. The expanded metal sheet can achieve even distribution to throughout the active area without the use of conventional channels.

Abstract: A pressure vessel for storing a compressed gas comprises a closed pressure vessel housing which consists of an essentially cylindrical main part and of closing caps located on both sides. The pressure vessel also comprises an integrated control device for delivering the gas including a pressure reducer with a high-pressure part and a low-pressure part and including a controlled gas outlet. At least one of the closing caps is a part that is assembled with the cylindrical main part and the majority of the components of the control device are mounted on this part and are directed inside the vessels housing.
