Abstract

The rapid reduction of the fossil fuel sources encourages the usage of the renewable energy (RE) as the alternatives source of electricity. Proton Exchange Membrane (PEM) fuel cell is one type of RE that recently being explored by the researches. In Malaysia, the application of PEM fuel cell is not yet been commercialise for the residential application. Besides, the characteristics of the PEM fuel cell can be rapidly changed due to few factors. Hence, the two of the main factors are humidity and temperature. Therefore, the effect of humidity and temperature towards the characteristics behaviour of PEM fuel cell have been studied and analysed. Hence, the signal analysis of the characteristics behaviour of PEM fuel cell is done using the signal processing technique. Humidity percentage is varied into two levels in order to analyse the characteristics performance of PEM fuel cell at various load currents. Meanwhile, the temperature is varied into a range of values and the load current is varied. Besides that, the performance characteristics analysis is used to analyse the characteristics behaviour of PEM fuel cell. In part of that, new technique which is signals processing techniques using periodogram is introduced. Therefore, the signal identification of humidity and temperature towards changing behaviour in PEM fuel cell can be investigated. The experiment proved that by increasing the humidity from 0% humidity to 80% humidity, the voltage of the PEM fuel cell increase to 5.95%, meanwhile by increasing the temperature from 20˚C to 40˚C, there is about 0.8V of PEM fuel cell voltage can be increases. It shows that the parameters of humidity and temperature influencing the performance of the PEM fuel cell. By increasing the humidity and temperature values, the performance can be escalating at optimum values.
