Fuel cells are electro-chemical devices that convert chemical energy into electricity.
They can be used as a mean to provide power for automobiles and other industrial and engineering devices. In this talk, we will provide background information for a special type of fuel cells. We will present a simple mathematical model to study mass transport inside fuel cell electrodes and discuss several aspects of our model, including the advantages and pitfalls, and some computational issues. Numerical results are also given. Determining the asymptotics of such a recurrent sequence is in general a difficult problem.
