This class of enzymes [EC 3.6.1.36] (also known as the hydrogen/potassium-exchanging ATPase, the potassium-transporting ATPase, proton pump, and the gastric H+/K+ ATPase) catalyzes the hydrolysis of ATP to ADP and orthophosphate, coupled with the exchange of and ions. The gastric mucosal enzyme has been the best characterized. [Pg.72]

Proton exchange membranes (PEM) fuel cells (or polymer electrolyte fuel cells - PEFCs), with H -conducting polymeric membranes, transports hydrogen (fuel) cations, generated at the anode, to an ambient air exposed cathode, where they are electro-oxidised to water at low temperatures. [Pg.52]

Proton exchange membrane (PEM) fuel cells are the primary choice for transportation systems, but they can also be useful for stationary power production or local hydrogen production. Most of the challenges of PEM fuel cell commercialization center around cost and materials performance in an integrated system. Some specific issues are the cost of catalyst materials, electrolyte performance, i.e., transport rates, and water collection in the gas diffusion layer (GDL). [Pg.345]

The membrane layer consists of a pol3mrier structure capable of transporting hydrogen ions with high conductivity, inspiring the name "proton exchange membrane". The membrane is thus a solid electrolyte. For the current emphasis on PEM fuel cells operating below 100°C, the Nation (trademark of... [Pg.184]
