Computer simulation of a polymer electrolyte membrane fuel cell (PEMFC)
The virtual models have a very important role in the development of fuel cells and to facilitate the understanding of the parameters that affect the operation of the system, also saving time and resources would be lost if built physical prototypes of the systems.
In general the system consists of the following elements: the air compressor input, packaging systems for gas entrance, a stack of membranes exchange and collectors inbound and outbound. To make the simulation using the Simulink® package, the software included in Matlab®. The simulation is considering addresses each block separately, but with inputs and outputs connected in each of them. We assume the same conditions of temperature in all parts of the stack, as the starting time of the PEMFC is small, operating at maximum temperatures of around 90 º C, and further periods of duration of the simulation used are short.
Once the model can be used in the sizing of energy systems and their integration with other models in energy systems more complex
The results show that the model is perfectly valid in power ranges from 0 to 15 kW, and that their behaviour is similar to the real system.
