cogeneration project based Fuel Cell

Project conducted in December 2000 C. Martz, C. and J. Stefani Vilquin. It is a small technoco-economic comparative concerannt cogeneration based on a low power fuel cell.

Introduction: Overview of Fuel Cells (PAC)

A fuel cell is a generator that directly converts the internal energy of a fuel into electrical energy, using a controlled electrochemical process (instead of a high temperature combustion reaction, the mechanical working is then converted to electricity generating mechanical and significant thermal losses). The expected theoretical yields are very high, and the by-products very little pollutants. What makes CAP make it a very likely alternative to the combustion engine (gasoline, diesel), for most of its applications.

It involves, without mixing a fuel (hydrogen, methanol, carbon monoxide ...) and an oxidant (generally oxygen taken from the air). Next the required power, it is composed of more or fewer assembly of elementary cells, that include a cathode chamber (supplied with oxidant) and an anode chamber (supplied with fuel), separated by two electrodes (that channel electrons), and an intermediate electrolyte, solid or liquid depending on the type of battery ....
