Abstract: The present subject matter pertains to PolyMET plate for a Proton Exchange Membrane fuel cell where the PolyMET plate includes a body made of a polymeric material and comprise a first surface and a second surface opposite to the first surface. Furthermore, the PolyMET plate includes a plurality of in-plane conductive pathways on the first surface defining a reaction area on the first surface, where the plurality of in-plane conductive pathways is formed as a coating of conductive material on the first surface. Moreover, the PolyMET plate also includes a through-plane conductive pathway formed of a solid conductive material extending between the first surface and second surface, such that the through-plane conductive pathway is electrically coupled to the in-plane conductive pathways.

Abstract: The present invention discloses a single stage energy efficient process for production of hydrogen enriched/mixed gas at low temperature. More particularly, the present invention discloses a single stage energy efficient process for production of hydrogen enriched compressed natural gas (CNG) or LPG or biogas at low temperature.

Abstract: An apparatus for purifying impure hydrogen fuel is described that includes a first chamber and a second chamber. The first chamber is configured to receive impure hydrogen fuel in the form of a first mixture of gases with hydrogen gas and carbon monoxide at the first concentration while the second chamber is configured to receive a second mixture of gases with hydrogen gas at the second concentration. The apparatus also includes a solid-state electrolyte that separates the first chamber and the second chamber and includes an adsorbing catalyst. The apparatus also includes a pair of electrodes installed each in the first chamber and the second chamber to create a potential difference is created across the solid-state electrolyte.
