Abstract
As we are seeing today, world is in a crisis of air pollution due to inevitable usage of fossil fuels in automobiles to run. The pollution is mainly due to emission of toxic gases such as carbon monoxide and oxides of nitrogen. There is a immense need of creating an alternate source of energy which reduces the level of emissions. Fuel cell is a device that can produce electricity without the generation of any pollutants when operated on pure H2 fuel. Low temperature polymer electrolyte membrane fuel cells operate at around 80 oC and water management in these cells becomes a challenge. This problem can be cirumvented if the cell can be operated above 100 oC. High temperature polymer electrolytic membrane fuel cells operate in the range of 120 oC to 200 oC with phosphoric acid doped polybenzimidazole as membrane electrolyte [4]. Modelling helps in understanding the deep insight of fuel cell processes thereby facilitates the improvement without involving any experimental work. In our work 1-D model is formed and resolved along the thickness of MEA. Validation of model is done for [1],[3] and [10] by generating polarization curves, cathode and anode overpotentials, and CO dynamic response.
