| Summary: | and air -- were tested. Results of these experiments were carbon cloth electrode material, such as electrical compression level exists for PEFC systems which provides compression levels. Compression was found to have a compression on PEFC performance. A new PEFC structure was compression on PEFC performance. Electrode compression was concluded from the findings of this work that the performance conditions. conductivity and porosity, were determined over a range of configuration which provided optimal performance. It was determination of the level of electrode compression. developed which provided uniform mechanical pressure distribution over the area of the electrodes and allowed electrode compression was found for each fuel cell found to have a significant effect on the performance of the further testing to measure the effects of electrode identified as a design parameter having a possible effect on of PEFC systems utilizing porous carbon cloth electrodes is of the PEFC system. Performance-affecting properties of the operated under various levels of electrode compression, and optimal performance under a given set of operating PEFC systems observed in this investigation. A level of plotted in a manner to illustrate the effect of electrode polymer electrolyte fuel cell (PEFC) were investigated. porosity of the carbon cloth electrode material, justifying Preliminary testing showed that considerable compression of significant effect on the electrical conductivity and significantly affected by the level of compression placed on sizes using two different cathodic reactants -- pure oxygen structure. Further, the level of electrode compression was sweep voltammetry technique. Fuel cells of two different the carbon cloth electrodes was provided by the PEFC The effects of electrode compression on the performance of a the electrodes. It was further concluded that an electrode the properties of the electrodes as well as the performance their electrical power output was measured using a linear- Utilizing this structure, several fuel cell systems were |
