Polymer exchange membrane

Hydrogen-powered cars are based on fuel cells that store hydrogen, or H2 gas, inside a material called a polymer exchange membrane. The fuel cell contains two electrodes an anode (negative side) and a cathode (positive side). At the anode, the H2 molecules are split into protons and electrons. The protons pass through a polymer exchange membrane, while the electrons are unable to pass through this membrane and thus have to flow in a different direction. This creates a current of electricity by which the car is powered. [Pg.185]

In recent years, it has evidenced a remarkable progress using solid-state MAS NMR to monitor the structure and dynamics, especially hydrogen bonding network and proton dynamics of polymer exchange membrane. Suarez and Greenbaum have reviewed the contribution of NMR spectroscopy to the development of the PEMFC, with particular emphasis on its use in the characterization of structure and transport in polymer electrolyte membranes [3]. Graf reviewed the application of 2D rotor-synchronized... [Pg.157]

In PEMFCs, electrode layers are the place where electrochemical reactions take place, made up of catalyst and GDL. At the anode, the hydrogen is broken into protons and electrons. The electrons firstly travel to the carbon cloth, flow field plate followed by the contact, and then to the load. The protons travel through the polymer exchange membrane to the cathode. At the cathode catalyst layer, oxygen combines with protons and electrons, and then water is produced. The catalyst layer must get very effective when breaking molecules into protons and electrons with large... [Pg.545]
