Platinum　loading　and　electrolyte　content　affect　the　surface　area　of　electrochemical　reaction　and　proton　conductivity,　respectively,　and　protons　and　oxygen　are　not　uniformly　distributed　in　the　catalyst　layer.　Therefore,　platinum　loading　and　electrolyte　content　can　be　set　to　be　simultaneous　non-uniform　distributions　to　further　enhance　the　species　utilization　and　cell　performance.　In　this　study,　a　non-isothermal,　two-dimensional,　two-phase　fuel　cell　model　is　set　up　and　coupled　with　the　catalyst　layer　agglomerate　model.　The　electrolyte　content　and　platinum　loading　uneven　distributions　influence　on　products　and　reactants　transmission　and　electrical　property　is　explored.　Results　indicate　that　electrolyte　volume　fraction　and　platinum　loading　coinstantaneous　graded　distribution　is　more　helpful　in　the　species　transfer　and　electrical　property　improvement.　The　maximum　power　density　of　coinstantaneous　graded　distribution　of　platinum　content　and　electrolyte　loading　along　the　channel　direction　is　increased　by　3.40%　compared　with　the　uniform　distribution,　and　is　2.94%　higher　than　the　superposition　of　the　maximum　power　density　when　the　graded　distributions　of　electrolyte　volume　fraction　and　platinum　loading　are　separately　set.　Moreover,　the　platinum　content　and　electrolyte　content　gradient　distributions　do　not　make　liquid　water　saturation　present　an　evident　segment　variation　along　the　channel　direction,　while　the　opposite　is　true　for　oxygen　concentration.　©　2023　Elsevier　Ltd
