Abstract:
A three-dimensional numerical analysis is performed to estimate the effect of divergent fuel channel on the reforming performance and non- isothermal reactant transport in a plate-shape reactor under methanol steam reforming and water-gas-shift reactions. The hydrogen yield was then employed to evaluate the net power output from a proton exchange membrane (PEM) fuel cell. These results display that the application of divergent fuel channel to plate-shape reactors plainly betters the hydrogen production from a reformer and net PEMFC power output. As compared to an ordinary reactor, the novel reactor with the divergent fuel channel of Hₒᵤₜ/Hᵢₙ = 4.0 creates the most notable improvement in the hydrogen production of 24.03 %. Furthermore, this novel reactor also gains the greatest advance of 6.39 % in the net power output form a PEMFC under implementing the pressure drop for the reactor channel.
