In　order　to　improve　catalytic　activity　and　stability,　alloying　Pt　with　a　non-noble　metal　has　proved　to　be　a　successful　strategy　for　the　development　of　new　electrocatalysts　for　low　temperature　fuel　cell.　An　alloy　is　a　mixture　containing　two　or　more　metallic　elements　or　metallic　and　nonmetallic　elements　usually　fused　together　or　dissolving　into　each　other　when　molten.　Solid　solution　is　the　alloy　when　two　metals　(　or　nonmetallic)　are　completely　soluble　in　liquid　state　and　also　completely　soluble　in　solid　state.　Usually,　the　atomic　positions　and　stoichiometric　of　the　solid　solution　are　uncertain,　for　example,　commercial　electrocatalyst　PtRu　alloy.　Intermetallic　compound　is　a　compound　of　two　or　more　metallic　elements　or　metallic　and　nonmetallic　elements.　Usually,　the　atomic　positions　and　stoichiometric　of　the　intermetallic　compound　are　fixed.　Pt-based　intermetallic　compounds　have　been　paid　more　and　more　attentions　by　researchers　due　to　its　many　excellent　properties.　In　this　review　paper,　we　present　the　recent　progress　of　Pt-based　intermetallic　compounds　used　in　low　temperature　fuel　cell.　The　synthesis　method　and　some　Pt-based　intermetallic　compounds　are　present.　The　future　development　of　this　research　field　is　prospected.
