Enhancement of PEM fuel cell performance by flow channel indentation
A three-dimensional, steady, single-phase flow of oxygen, nitrogen and water vapor mixture in the cathode of proton exchange membrane (PEM) fuel cell was numerically studied here. It was shown that the performance of the cell was enhanced by partial blockage of the flow channels in a parallel flow field. Since, channel indentation could increase oxygen content within the catalyst layer. It was ...
متن کاملReaction Dynamics in a Parallel Flow Channel PEM Fuel Cell
The spatiotemporal dynamic response of a segmented anode parallel channel polymer electrolyte membrane PEM fuel cell was monitored following changes in flow rate, temperature and load resistance. Autohumidified operation with dry feeds at 1 bar pressure was achieved at temperatures below 70°C, where the convective transport of water vapor was less than the water production by the fuel cell curr...
متن کاملParametric study of the influence of cooling channel dimensions on PEM fuel cell thermal performance
In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...
