The　dynamic　response　characteristic　is　an　important　performance　indicator　of　the　proton　exchange　membrane　fuel　cell　(PEMFC),　which　has　a　great　influence　on　the　durability　and　reliability.　The　cooling　capacity　is　an　important　factor　that　affects　the　stability　of　the　PEMFC　output　after　the　change.　This　research　proposes　to　apply　the　micro-heat　pipe　array　(MHPA)　to　the　thermal　management　of　PEMFC.　A　novel　MHPA-PEMFC　stack　is　designed,　and　four　cases　involving　comparative　dynamic　response　experiments　are　studied.　The　results　show　that　compared　with　the　traditional　air-cooled　PEMFC,　the　MHPA-PEMFC　significantly　reduces　the　maximum　step　voltage,　dynamic　internal　resistance　and　step　temperature,　shortens　the　temperature　response　time　and　improves　the　internal　temperature　uniformity.　In　the　case　where　the　output　current　stepped　up　from　10　to　30　A,　the　maximum　step　voltage　and　the　maximum　dynamic　impedance　of　MHPA-PEMFC　are　lower　than　those　of　PEMFC　by　0.449　V　and　0.037　omega,　respectively.　The　maximum　step　temperature　has　been　reduced　by　4.44　degrees　C,　and　the　temperature　response　time　has　been　reduced　by　180　s.　The　research　results　provide　a　basis　for　using　MHPA　in　PEMFC　thermal　management　applications.
