This study performed three-dimensional numerical simulations to observe the effect of convergent fuel channel on the non-isothermal reactant transport and reforming performance in a plate-shape reactor under methanol steam reforming. Furthermore, the hydrogen production was utilized to estimate the net power output from a PEMFC. The results reveal that the application of convergent fuel channel to a plate-shape reactor evidently improves the hydrogen yield from reformer and estimated net power output from PEMFC. Compared with a common reactor, the novel reactor with the convergent fuel channel of Hout/Hin = 0.25 produces the greatest improvement in the hydrogen yield of 34.85%. However, the novel reactor with the convergent fuel channel of Hout/Hin = 0.5 earns the maximum rise of 8.84% for the estimated net power output form a PEMFC under considering the pressure drop through the channel.
