Dynamic Analysis of the Proton Exchange Membrane Fuel Cell

Abstract

Hydrogen energy fuel cell is one of the clean/green energy solutions for the environmental pollution, global warming, and petroleum energy shortage. This study investigates the dynamic characteristic of the green hydrogen energy fuel cell: Proton Exchange Membrane Fuel Cell (PEMFC). PEMFC has been adopted to be the power supplier of the vehicle, small train, etc. A lot of researchers aim on pure electrical property analysis. However, to put PEMFC power system on the road, some mechanical properties of the system should also been examined. In this paper, the dynamic characteristic of a single PEMFC is studied. A single PEMFC (L112×W82×D6 mm) is set up and measured for the time and frequency response. Several fundamental modes are found experimentally which should be avoid during operation period of PEMFC especially in a moving vehicle.
