Testing of PEMs

During the last 2 years, the performance of the perfluorosulfonic acid PEMs, its instabilities, water absorption, diffusion, and activities of water in it as well as effects due to chain flexibility were investigated by several research teams [196-200]. Thermal and hydrolytic stability of sulfonated polyimides was investigated by Han and coworkers [201]. [Pg.36]

The EU s "FURIM" program targets the development of novel PEM membranes and related components for high temperature fuel cells and the testing of PEM stacks to evaluate their technical, economic and environmental impacts. Thirteen European partners are involved in the 4 million project. The EU s Hj-MINIPAC is focused on the development of micro PEM fuel cells using hydrogen as a fuel. [Pg.31]

The Institute of Chemical Engineering and High Temperature Chemical Processes (ICE/HT) works on design, construction and testing of PEM components, electrochemical reactions/reactors, electrocatalysts for PEMs, hydrogen production by catalytic processes and water splitting. [Pg.139]

Ex situ degradation testing of PEMs is conducted via Fenton reactions. Ferrous iron (II) is oxidized by hydrogen peroxide (H2O2) to hydroxyl radicals (OH ) and ferric iron (III) which is reduced back to iron (II) and hydroperoxyl radicals (OOH ) during the disproportionation step (Haber and Weiss, 1932 Walling, 1975 and 1998 Lindsey and Tarr, 2000, Knndn et al, 2008). [Pg.214]

Accelerated testing is often used to rapidly evaluate a PEM fuel cell design and screen the various component materials. Such testing is often conducted under very stressful conditions, such as open circuit voltage (OCV), high temperature, high current density, and the like. Accelerated testing of PEM fuel cells is covered in Chapter 11. [Pg.92]

This phased program includes the fabrication and testing of three 10-kW subscale PEM fuel cell stacks leading up to the final 50 kW system. Stack technology development and system analysis were conducted iteratively to identify pertinent technology advances to be incorporated into successive subscale stack builds. The final system analysis will define the 50 kW stack and system configuration. [Pg.369]

Several properties of cellulose phosphate have been evaluated. The material has good thermal stability and low hydrogen crossover, two requirements that are important to meet DOE fuel cell program targets. Further characterization of the material is required, especially the determination of proton conductivity. In addition, testing of the material in an MEA will allow the effect of acid stability and swelling properties of cellulose phosphate be evaluated under typical PEM fuel cell operating conditions. [Pg.406]
