Description
Technical field
The utility model is related to a kind of fuel cell cooling control systems, and cooling water quality control is carried more particularly, to one kind
The integral new-energy passenger fuel cell system of system.
Background technology
Fuel cell is a kind of power generator of electrochemistry, and isothermal presses electrochemical means, is directly converted into chemical energy
Electric energy by Carnot cycle without through overheated machine process, not limited, thus energy conversion efficiency is high, and noiseless, pollution-free, just
As ideal energy utilization patterns.In theory, as long as continuously supplying fuel, fuel cell just can continuously generate electricity,
It is the forth generation generation technology after waterpower, firepower, nuclear power to be known as.Business-purpose fuel cell " the matter being currently being deployed
It has higher energy efficiency and energy density to proton exchange film fuel cell ", and volume weight is small, and the cold start-up time is short, operation
Securely and reliably.In addition, its dielectric film used is solid-state, electrolyte corrosion can be avoided, is had excellent performance.Height as 21 century
Sci-tech product, fuel cell have been applied to the industries such as auto industry, energy power generation, shipping industry, aerospace, domestic power supply,
Paid attention to by national governments.
Fuel battery inside is mainly made of proton exchange membrane, electro chemical catalyst, diffusion layer and bipolar plates.Work as combustion
It is internal that following reaction process occur when expecting battery work：Reaction gas is spread in diffusion layer, is catalyzed when reaction gas reaches
During layer, by Catalyst Adsorption and electrocatalytic reaction occurs in Catalytic Layer；The proton of anode reaction generation passes through proton exchange membrane
Inside it is transmitted to cathode side, electronics reaches cathode through external circuit, with oxygen molecule reaction bonded Cheng Shui,
Release heat simultaneously.Electrode reaction is：
Anode (cathode)：H2→2H++2e
Cathode (anode)：1/2O2+2H++2e→H2O
Cell reaction：H2+1/2O2→H2O
Due to proton exchange membrane can only proton conducting, hydrogen ion (i.e. proton) can reach directly through proton exchange membrane
Cathode, and electronics can only get to cathode by external circuit.Direct current is just produced when electronics flows to cathode by external circuit

The humidity that film needs to keep certain is changed, reacting the water of generation needs to exclude.Migration, transmission, generation, the condensation of the water of different shape
All have a significant impact to the stable operation of pile, water, heat management this generates proton exchange membrane fuel cell power generation system
Problem.Under normal conditions, pile is both needed to using complicated humidification auxiliary system for humidifying proton exchange film, in case electrode is " dry
Extremely " (proton exchange membrane proton conducting ability declines or even damage)；The water of generation must be discharged in time again simultaneously, with anti-electric
Pole " drowned ".Since the running temperature of Proton Exchange Membrane Fuel Cells is generally at 80 DEG C or so, its Operating ettectiveness is best at this time, because
This reaction gas needs to preheat before entering pile, this process is usually carried out at the same time with the humidification of gas；Pile generates electricity
When the heat that generates will increase stack temperature, it is necessary to appropriate cooling provision is taken, to keep Proton Exchange Membrane Fuel Cells
Pile operating temperature is stablized.These are usually adjusted with heat exchanger and pure water humidifying device, and are coordinated with computer
Control.
In order to ensure the normal work of proton exchange film fuel cell electric piling, usually by pile, hydrogen and oxygen treatments applied system
System, hydro-thermal management system and corresponding control system carry out mechatronics integration, form Proton Exchange Membrane Fuel Cells power generation
Machine.And when fuel cell generation is used as vehicle, ship when the dynamical system of delivery vehicles, fuel cell generation, which is called, to be done
Fuel battery engines.
The common test platform of Proton Exchange Membrane Fuel Cells now is typically all to be formed with microcontroller and application software
With monitoring test system.Fuel cell is installed to test platform, tests three flow field hydrogen flow fields, flows of system
Field, air flow field inlet and outlet are respectively provided with the sensors of various acquisition signals, such as：Flow, temperature, pressure, humidity, electricity
The sensor of the various analog quantitys such as stream, voltage.Test system is according to the gathered data of various sensors come to each of fuel cell
Item test provides relevant data reference, and foundation is provided for properties of product assessment.But the fuel electricity on car is applied at present
Ion combination can be precipitated due to the radiator of cooling system, water pump, water lines parts material in pond engine system at work
Object causes water conductivity in fuel cell water installations to rise, is electronically generated, leads in ion interference fuel-cell device in cooling water
Fuel-cell device loss of electrons is caused, monomer output power declines, and influences fuel cell output whole efficiency.
