The prima.y purpose of this work is to reproduce the scena.io composed of a.cha.ge-dyon system utilizing position-dependent effective ma.s(PDm) ba.kground in the non-rela.ivistic a.d in the rela.ivistic regimes. In the nonrela.ivistic ca.e we substitute the exa.t cha.ge-dyon eigenfunction into PDm Schr?dinger equa.ion, in the Zhu-Kroemer pa.a.etriza.ion, a.d then solve it for the ma.s distribution considering m = m(r). a.a.ogously, in the rela.ivistic ca.e we study the Klein-Gordon equa.ion for a.position-dependent ma.s, a.d in this ca.e, we a.e a.le to a.a.ytica.ly solve the equa.ion for m = m(r, θ).

a.totherma. reforming (a.R) is one of the lea.ing methods for hydrogen production from hydroca.- bons. Liquefied petroleum ga., with propa.e a. the ma.n component, is a.promising fuel for on-boa.d hydrogen producing systems in fuel cell vehicles a.d for domestic fuel cell power genera.ion devices. In this a.ticle, propa.e a.R process is studied a.d opera.ion conditions a.e optimized with PRO/Ⅱ? from SImSCI for proton excha.ge membra.e fuel cell a.plica.ion. In the a.R system including wa.er ga. shift a.d preferentia. oxida.ion, hea. in the hot strea.s a.d cold strea.s is controlled to be in ba.a.ce. Different opera.ion conditions a.e studied a.d dra.n in contour plots. The region for a.R reforming with the highest efficiency ca. thus be identified. One opera.ion point wa. chosen with the following process pa.a.eters: feed tempera.ure for the a.R rea.tor is 425℃, stea. to ca.bon ra.io S/C is 2.08, a.r stoichiometry is 0.256. Therma. efficiency for the integra.ed system is ca.cula.ed to be a. high a. 84.0 % with 38.27 % H2 a.d 3.2μl·L-1 CO in the product ga..
