STACK OF HYDROGEN ION EXCHANGE FUEL CELL

摘要

PURPOSE: Provided is a stack of a hydrogen ion exchange fuel cell, which can be assembled and dismantled easily and can diffuse fuel and air effectively and can radiate heat effectively and has increased fuel efficiency. CONSTITUTION: The stack of the hydrogen ion exchange fuel cell comprises at least two unit cells(10) accumulated and the unit cell(10) comprises a catalyst-treated membrane(11), which is an electrolyte membrane catalyst-treated on the both sides thereof, a fuel flow field(12) and an air flow field(15) placed on the both sides of the catalyst-treated membrane(11), and bipolar plates(13) in contact with the outsides of the fuel and air flow fields(12)(15). At least one of the fuel flow field(12) and the air flow field(15) contains a parallel flow field member(12b)(15b) inducing the flow of gas in parallel direction with the catalyst-treated membrane(11) and an orthogonal flow field member(12a)(15a) inducing the flow of gas in vertical direction to the catalyst-treated membrane(11), wherein the parallel flow field member(15b) of the air flow field(15) contains a serpentine air flow channel.
