  Fuel Cell background information
A fuel cell is an electrochemical device which brings together hydrogen and oxygen, or air in the midst of a catalyst to produce electricity, heat and water.
This type of fuel cell is still in the design stages because of the problems of finding a good electrocatalyst to both, transform methanol into carbon dioxide and hydrogen efficiently and to reduce oxygen in the presence of methanol should any transfer through the electrolyte which is in itself a problem (1, 7, 8).
A fuel cell generates power though a voltage difference and current, therefore electrical separation of the poles is required in order not to short the cell thus subverting all current through the short and not through the load.
