Description
Technical field:
The present invention relates to a proton exchanging film fuel battery.
Background technology:
Proton Exchange Membrane Fuel Cells (proton exchange membrane fuel cell, PEMFC) be a kind of low-temperature fuel cell, it is fuel with hydrogen, with the air or oxygen is oxidant, it is the green energy resource of realizing using regenerative resource (hydrogen) and zero discharge (its unique emission is a water), be the first-selected power supply of fuel cell car, and be widely used in civilian and the national defence field as portable power source.At present, Proton Exchange Membrane Fuel Cells mostly is plate and frame (plate) structure, heavy and the bulky deficiency at the flat fuel cell quality, the researcher has proposed to design the PEMFC of other structure, as make tubular fuel cell, need not be with the conceptions such as bipolar plates in flow field, to reach the ancillary equipment of simplifying battery, improve volume of battery specific power and quality than power, reduction cost of manufacture, shortening manufacturing cycle, satisfy the load instructions for use that volume is little, in light weight, power requirement is not high.
Self-breathing prorton exchange membrane fuel cell (Self-breath Proton ExchangeMembrane Fuel Cell, Self-PEMFC) directly use hydrogen to make fuel, hydrogen supply gas is hydrogen container or add hydrogen storage material in addition, really reach the use of zero new forms of energy that pollute, very long-range Research Significance is arranged for the strategy of sustainable development of the energy.Therefore, rapid to the development and application development of PEMFC technology in recent years, all research and development have spent huge manpower and material resources to PEMFC for domestic and international many colleges and universities, institute and each major company.The emphasis of research is exactly the cost that reduces PEMFC, improves the performance of PEMFC, is fit to commercialization and uses.
The PEMFC of circular configuration as portable electric device electrokinetic cell and domestic power supply the time, has unique advantage.The research report is abroad arranged, and the research of circular PEMFC just begins, and the development aspect of the selectable material of membrane electrode, preparation technology and small-sized pile mostly is research paper, and commercial product is not arranged.
Circular Proton Exchange Membrane Fuel Cells is the same on basic principle with present square Proton Exchange Membrane Fuel Cells, but structurally owing to be that circular volume reduces greatly, volume of battery specific power and quality increase than power, manufacturing cost reduces, manufacturing speed is accelerated, and adopts significant to the popularization of Proton Exchange Membrane Fuel Cells.But because structural change then has a great difference, so need carry out many researchs in design and manufacturing.
Therefore,, improve the performance of battery, reduce production cost of cells, can promote the PEMFC commercial applications by improvement to circular PEMFC battery pack general structure and each modular construction.
