Description
Technical field
The present invention relates to a kind of fuel cell system, and be particularly related to a kind of fuel cell system that can discharge its internal reaction generation gas.
Background technology
Fuel cell (Fuel Cell, FC) be a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) of utilizing chemical energy to be converted into electric energy, under traditional generation mode comparison, fuel cell has low pollution, low noise, high-energy-density and higher advantages such as energy conversion efficiency, be to have following prospective clean energy, applicable scope comprises various fields such as portable electric product, household system, means of transportation, military equipment, space industry and large generating system.
Common fuel cell can be divided into following five kinds substantially according to employed electrolytical kind:
1. alkaline fuel cell (AFC): with potassium hydroxide is electrolyte;
2. carbonic acid fuel cell (PAFC): with the phosphoric acid solution is electrolyte;
3. molten carbonate fuel cell (MCFC): with carbonic acid thing fusion back as electrolyte;
4. solid eleectrolyte fuel cell (SOFC): mainly with zirconium dioxide as electrolyte; And
5. Proton Exchange Membrane Fuel Cells (PEMFC): comprise so-called direct methanol fuel cell (DMFC), be fuel directly, and need do not form hydrogen in advance with methyl alcohol.
Wherein, direct methanol fuel cell (DMFC) is originated as fuel supply because of directly using the methyl alcohol of liquid state or gaseous state, and need not supply the usefulness of generating with other materials such as reorganization methyl alcohol, gasoline and natural gases with generation hydrogen by reformer, it has low temperature and gives birth to characteristics such as electric, that the dangerous low and living electricity of propellant composition is simple in structure, so makes direct methanol fuel cell become the main flow that portable electronic product is used gradually.
Known direct methanol fuel cell mainly is to be made of mea (Membrane ElectrodeAssembly is called for short MEA), anode collector plate and cathode collector plate.Mea be by proton-conductive films (Proton Exchange Membrance), anode catalyst layer, cathode catalysts layer, anode gas diffusion layer (Gas Diffusion Layer, GDL) and cathode gas diffusion layer constitute.Wherein, above-mentioned anode catalyst layer and cathode catalysts layer are disposed at the both sides of proton-conductive films respectively, and anode gas diffusion layer and cathode gas diffusion layer are separately positioned on anode catalyst layer and the cathode catalysts layer.Anode collector plate and cathode collector plate are to be arranged at respectively on anode gas diffusion layer and the cathode gas diffusion layer.The reaction equation of direct methanol fuel cell is as follows:
Positive C H
3OH+H
2O → CO
2+ 6H

Can be understood by reaction equation (1), when direct methanol fuel cell was operated, its anode partly had CO
2Produce, for fear of the excessive gas pressure of anode accumulation, must be in time with CO
2From fuel cell system, get rid of, when anode uses liquid fuel, CO
2Be easy to get rid of with fluid separation applications, but in the battery system that uses fuel gas, fuel gas and CO
2Can't delamination and may make fuel gas along with CO
2Be discharged into outside the system together, cause waste of fuel, influence the fuel conversion efficiency of fuel cell, again, can provide the anode layer of preserving moisture to make gasification of methanol can pass the anode layer of preserving moisture to enter anode gas diffusion layer, but the aqueous vapor of same anode also can be passed preserve moisture layer and diffuse to the fuel storage groove of anode, causes the fuel concentration in the fuel storage groove diluted, and can cause the internal resistance value of membrane electrode resistance to rise, for example the WO2005/112172A1 patent application case discloses.In addition, CO can further be set
2Floss hole is in the sidewall of vaporising fuel reception room, and for example the WO2006/040961A1 patent application case discloses, and the gasification of methanol concentration of this vaporising fuel reception room is only second to the fuel storage groove, but therefore causes more gasification of methanol along with CO
2Discharge, not only pollute surrounding environment, fuel efficiency is descended.
