Technical field
The field that the utility model relates to is direct methanol fuel cell, is specifically related to a kind of stacked passive direct methanol fuel cell group based on polymer bipolar end plates.
Background technology
Direct methanol fuel cell (DMFC) is as a kind of minitype portable energy, and higher specific energy and energy conversion efficiency are its main advantages that attracts people.Fixing external structure and the liquid fuel that can fill at any time simultaneously, be also user's condition of providing convenience, and it is simple in structure, and the response time is short, operates also very convenient.With respect to active direct methanol fuel cell, passive direct methanol fuel cell does not need as active auxiliary equipment feed fuels such as pump, fans, directly utilize the principles such as diffusion and free convection to carry out fuel supply to battery, not only greatly reduce the complexity of battery system, be conducive to integrated application, and reduced parasitic energy loss, improved the energy density of battery system.Current passive direct methanol fuel cell group mostly is planarized structure, and by 6 joints or to be less than 6 joint list ponds integrated, this structure is subject to the restriction of usage space for the integrated meeting of more piece (being greater than 10), and integrated level is lower.And traditional polymer plated film bipolar plates poorly conductive, is difficult to meet the demand of high-power output.
Summary of the invention
The utility model is for the deficiencies in the prior art, a kind of stacked passive direct methanol fuel cell group based on polymer bipolar end plates is provided, solve passive direct methanol fuel cell group cannot more piece the integrated and lower problem of polymer plated film bipolar plates power.
Stacked passive direct methanol fuel cell group based on polymer bipolar end plates, comprises an anode polymer monopolar terminal plates, negative electrode polymer monopolar terminal plates, one or more polymer bipolar end plates, metal collector and a membrane electrode.Two polymer monopolar terminal plates are oppositely arranged on the two ends of battery pack, on relative two faces of two polymer monopolar terminal plates, be provided with the metal collector of monolithic, between two unitary piece of metal collector electrodes, be provided with the identical unit of a plurality of structures, each unit comprises four rubber cushions, two membrane electrodes, a polymer bipolar end plates and a biplate metal collector, by being linked in sequence of rubber cushion, membrane electrode, rubber cushion, polymer bipolar end plates, rubber cushion, membrane electrode, rubber cushion, biplate metal collector is arranged on the two ends of polymer bipolar end plates; Battery pack is connected in series according to the order of the metal collector of the metal collector of anode polymer monopolar terminal plates, monolithic, a plurality of unit, monolithic, negative electrode polymer monopolar terminal plates, and is bolted.
Described polymer bipolar end plates anode-side center is provided with square indentations, and cathode side is provided with gas feed groove;
The metal collector of described monolithic is stainless steel thin slice, and opens a plurality of through holes with transfer reaction thing,
Described biplate metal collector is two and is connected and the metal collector of the monolithic that be arranged in parallel, the biplate metal collector structure that is formed in one;
The metal collector of described monolithic and biplate metal collector carry out sputter or chemical plating is processed, and coating is Au, Pt or TiN;
Described center, anode polymer monopolar terminal plates side is provided with square indentations;
