Dynamic modelling of fuel cell system for mobile application using Simulink environment

Nowadays, the increment of the petrol price has been a major problem for the consumers and it will increase more than 4 cent per litter in period of 6 to 12 month. Thus, there are many new energy developments that friendly to the environment have been commercialized to overcome this phenomenon such as solar energy and fuel cells technology. Among these, fuel cell power systems for transportation applications have received increased attention in recent years because of the potential for high fuel efficiency and lower emissions. A fuel cell converts hydrogen and oxygen into water, directly generating electrical energy from chemical energy without being restricted by efficiency limits of the Carnot thermal cycle (Larminie et al., 2000)

Dynamic behaviour and sensitivity analysis of 5kW PEMFC stack simulation

This paper describes a three dimensional 5 kW PEMFC stack dynamic model. Both time and spatial dependence are considered. Dynamic response and sensitivity analyses of the stack are carried out using MATLAB and Simulink modules. The results highlights the three dimensional distributions of species concentrations, power density and temperature of model. The effects of feed flowrates on the stack power performance are illustrated. The results confirmed that the model developed as a reasonable representation of the fuel cell stack system
