The　catalyst　loading　random　distribution　has　a　divergent　effect　on　heat　transfer　and　electrical　property　inside　fuel　cells　than　the　catalyst　loading　homogeneous　distribution,　but　the　effects　of　different　stoichiometric　ratios　and　average　platinum　loadings　on　electrical　property,　heat　as　well　as　species　transfer　in　the　fuel　cell　considering　catalyst　content　random　setting　are　still　unclear.　Hence,　the　impacts　of　stoichiometric　ratios　and　average　platinum　loadings　on　the　electrical　property　of　fuel　cell　considering　catalyst　content　random　distribution　are　explored　in　this　paper　by　using　a　steady　state,　two-dimensional,　two-phase,　non-isothermal　fuel　cell　model　coupled　the　catalyst　layer　agglomerate　model　considering　the　multi-scale　problem　of　catalyst　layer.　Results　indicate　that　stoichiometric　ratio　and　average　platinum　loading　do　not　influence　the　effect　direction　of　catalyst　content　distributed　randomly　on　the　output　power.　However,　with　the　stoichiometric　ratio　rising,　the　impact　degree　of　catalyst　content　distributed　randomly　on　the　output　power　first　enhances　and　then　diminishes.　When　the　stoichiometric　ratio　is　1.3,　the　power　density　of　uniform　random　distribution　changes　the　most,　decreasing　by　3.91　%.　As　the　average　platinum　loading　rises,　the　impact　degree　of　catalyst　content　distributed　randomly　on　the　output　power　gradually　decreases.　The　power　density　of　uniform　random　distribution　decreases　by　4.93　%　when　the　catalyst　content　is　0.2　mg/cm2.　Furthermore,　the　variation　trends　of　temperature　distribution,　product　and　reactant　content　with　stoichiometric　ratio　and　average　platinum　loading　under　the　platinum　loading　random　distribution　condition　are　consistent　with　that　under　the　platinum　loading　homogeneous　distribution　condition.　However,　as　the　stoichiometric　ratio　rises,　the　reaction　rate　distribution　becomes　more　uniform　for　normal　random　and　homogeneous　distributions,　but　the　reaction　rate　distribution　becomes　uneven　under　uniform　random　distribution.
