Flow field is the important part in proton exchange membrane (PEM) fuel cell and one of its control factors. In this paper, the performance of PEM fuel cell with non-equipotent flow field was tested. Influences of the dimension change and the arrangement of flow field on its performance is analyzed. Experimental results show that comparison with conditional water management in PEM fuel cell with equipotent...
PEM fuel cell is a clean power with a wide application prospect. The water content in proton exchange membrane plays an important role on the performance of PEM fuel cell. In this paper, Performance of PEM fuel cell with the cathode up was measured under the condition of different operating parameters. Influence of the placement of cathode up on water content in proton exchange membrane is studied...
This paper deals with hydrogen technologies that seem to be very suitable for the storage of electrical energy from renewable sources (RES) with rapidly growing popularity in the Czech Republic - the wind power plants. The hydrogen fuel cells are a fundamental part of this storage system. The paper also describes their operating characteristics at long-term measurement. The conclusive part refers...
