Thermodynamic Analysis of Fuel Processor for Fuel Cell Vehicles

Abstract:

Thermodynamic analysis was carried out for theoretical reaction of hydrogen produced from dimethyl ether (DME) auto-thermal reforming by using the minimum of GIBBS energy. The volume content of various gases were calculated at adiabatic condition as function of air to DME ratio (0.2~0.8), H₂O to DME ratio (1~6) and pressure (0.1~0.6MPa). The result proves that the volume content of H₂ decrease with the increasing of pressure. With the increasing of the H₂O to DME ratio and the O₂ to DME ratio the volume of H₂ increases first then decreases. With the increasing of the H₂O to DME ratio the volume of CH₄ and CO decreases, the volume of CO₂ increases. The model reliability was verified experimentally on self-designed equipment. The experiments data are closed to simulation results.
