Description
Technical field
The invention belongs to technical field of new energies, relate to a kind of electric generator using fuel battery with proton exchange membrane of practicability.
Background technology
Fuel cell is a kind of uninterruptable power generation device that the chemical energy in fuel and the oxidant can be changed into electric energy by electrochemical reaction.Fuel cell technology mainly is divided into several types according to the electrolyte difference: alkaline fuel cell, phosphoric acid fuel cell, molten carbonate fuel cell, polymer electrolyte fuel cells and Solid Oxide Fuel Cell etc.Develop to such an extent that maturation and application prospect are that (Proton Exchange Membrane Fuel Cell PEMFC), is designated hereinafter simply as fuel cell to Proton Exchange Membrane Fuel Cells the most widely relatively at present.The core component of this device is membrane electrode (Membrane Electrode Assembly, MEA), membrane electrode is made up of the Catalytic Layer (adopting the preparation of Pt/C catalyst and ion conductor usually) and the diffusion layer (as carbon paper, wire netting etc.) of a slice ion exchange polymer film, the combination of film two sides.
Fuel cell is the open energy conversion device of a kind of electricity, heat, water three coproduction in fact.Be similar to internal combustion engine on the working method, and be similar to chemical power source on the operation principle.The generation of water fuel cell just has the main cause of the feature of environmental protection, and also will discharge a large amount of used heat when producing electric energy, and waste thermal energy that is produced and electric energy ratio are near 1:1.Therefore, PEMFC also must keep normal working temperature by suitable heat dissipation design in generating, otherwise the too high meeting of pile internal temperature causes the inefficacy of fuel cell, even causes danger.The radiating mode of PEMFC adopts two kinds of water cooling and air cooling methods usually.Water cooling is taken the used heat in the battery out of by cooling water, by external heat-exchanging heat is taken away again, and the cooling water after the cooling is recirculated into battery; The air cooling method is to take away used heat by pile that normal temperature air is forced to flow through, and concrete heat dissipation design depends on the watt level of fuel cell.Air cooling and water-cooling structure design respectively have pluses and minuses: air cooling system is simple, and cost is lower, only needs aerofoil fan and controller to get final product, the few reliability height of parts; The water-cooling system complexity, cost is higher, needs pure water, water pump, valve, water pipe etc., and the more reliability of parts is low, but also needs periodic replacement or purify cooling water.
