Description:
This paper presents an evaluation of the transfer coefficient of a reversible PEM fuel cell by using the Lagrange’s undetermined multiplier technique. In a first step, the technique using the activation polarization was presented. Then we put the stress on the Lagrange’s undetermined multiplier technique. The mathematical bases of this method are presented. Subsequently, an experimental determination of the transfer coefficient was carried out by using the two methods. For that purpose, a kit called Hydrocar, combining a solar panel, a reversible PEM fuel cell (which is a combination of fuel cell and electrolyser), hydrogen and oxygen storage containers, and a 3 Volts alkaline battery, was experimented. The experimental study of the solar panel was made. Some parameters of the solar panel were determined, such as the fill factor FF, the efficiency η, the short circuit current I SC , the open circuit voltage V OC , the maximum power P m , and the series...
