EXPERIMENTAL PERFORMANCE CHARACTERISTIC OF PEM FUEL CELL

Abstract

The motive of this paper work is to analyze the improvement of commercial fuel cell (rated capacity 1000W) with the help of resistive load and output power variation with change in H2 flow rate and calculate the maximum power point (MPP) of the proton exchange membrane (PEM) while changing AC and DC load respectively. The factors influencing the output power of a fuel cell are hydrogen flow rate, cell temperature, and membrane water content. The results show that when the H2 flow rate is changed from 11, 13, and 15 lpm, MPP is increased from lower to higher flow rate. The power of the fuel cell is increased at the rate of 29% by increasing the flow rate from 11 to 15 lpm. This study will allow small-scale industries and residential buildings (in remote or inaccessible areas) to characterize the performance of PEMFC. Furthermore, these cell helps in reducing the emission in the environment as fossil fuels produces a lot emission so to break this these fuels can be are of the best alternative for ecofriendly as well as cost effective these are renewable energy source which production increases day by day .
