Passive　micro　direct　methanol　fuel　cells　have　drawn　increasing　attention　because　they　are　a　promising　choice　of　next　generation　of　power　sources　for　portable　electronic　devices.　Micromation　and　passive　characteristic　bring　a　new　challenge　concerning　reactants　feeding　for　fuel　cell　reaction.　Most　ways　of　fuel　supply　in　passive　fuel　cell,　including　methanol　vapor　feeding,　direct　soak　anode,　carbon　dioxide　drove　liquid　feeding,　capillarity　and　surface　tension,　etc.,　are　reviewed.　An　analysis　and　discussion　of　distinguishing　feature　and　long-term　potential　are　conducted.
