The　PEMFC(Proton　Exchange　Membrane　Fuel　Cell)　possesses　the　advantages　of　high　energy　efficiency,　simple　structure,　zero-emission,　etc.,　which　has　great　development　potential　and　application　prospects.　Modeling　research　is　very　important　for　the　characterization,　structural　design,　and　control　strategy　analysis　of　PEMFC.　In　this　work,　a　comprehensive　PEMFC　model　is　proposed　based　on　simplifying　assumptions　and　operating　mechanisms.　The　model　consists　of　a　voltage　model,　an　anode　model,　a　cathode　model,　and　a　membrane　model,　and　considers　the　transmembrane　transport　of　water　and　gases.　In　addition,　the　model　is　designed　based　on　operating　conditions　and　physical　design　parameters　to　enable　a　more　accurate　characterization　of　the　fuel　cell.　The　influence　of　operating　conditions　on　the　output　characteristics　of　PEMFC　was　explored　using　the　developed　model.　The　developed　model　can　be　used　to　optimize　the　design　of　the　PEMFC.　©　2024　IEEE.
