This paper studies the charge conservation equation in the modeling of fuel cells. It is often useful to have an approximate closed form solution to describe the electronic potential in the whole solution domain. In our problem, no small term exists and the perturbation method cannot be used ...

Cellular respiration is a chemical reaction that occurs in cell organelles called mitochondria. This reaction allows energy from glucose in our food to be released so that it can be used to fuel cellular processes.Answer and Explanation: The chemical equation for cellular respiration is as follows:...
In previous studies, the fuel cell temperature has been assumed to be steady. However, the operation temperature of the fuel cell is not constant in the real fuel cell systems, such as residential and vehicular fuel-cell stacks. Therefore, it is difficult to separate the different types of ...
