Effect of fuel thermo physic parameters on electrical and energetic performances of fuel cell

Abstract

For the operation of a fuel cell, pure hydrogen gives the best results in terms of performance . But the choice of fuel does depend only on the fuel; there are other factors to be considered. In addition to the availability for the user through a distribution network, it is necessary to take into account the flow of energy from wells to the wheel and the technical problems of production, transport and storage of this fuel. Storing hydrogen on vehicle board is essentially limited by the volume and the weight assigned to the tank. Add to this, practical aspects of use and safety. This work gives a comparison of the thermodynamic properties of hydrogen pile and with alcohols fuels (methanol, ethanol) directly in a temperature range varying from 298.15 to 1273.15 K and a pressure varying from 1 to 10 atm and a molar concentration of oxygen ranging from 0.21 to 1
