Technical field
The utility model relates to fuel cell, relates in particular to a kind of fuel cell power generating system.
Background technology
The PEMFC fuel cell is a kind of H
2And O
2The chemical energy that reaction produces changes into the device of electric energy, and it has room temperature and starts transformation efficiency height, specific power density height, characteristics such as product zero pollution.Fuel cell applications is very wide, and large-scale fuel cell can be used as submarine, boats and ships, the power source of automobile etc.Vehicle-mounted large-scale fuel cell has become the exploitation focus of present fuel cell, and each big motor corporation of the world is all at the green energy resource automobile that steps up to research and develop zero discharge, and this is because the promotion of three aspects: protection environment, the deficient scarce and discharging policy of oil.In order to solve the petroleum resources deficiency, adapt to more and more stricter exhaust emission standard, reduce the serious day by day pollution that automobile brings, the environment that protection is human, the development electric automobile is the inevitable course.What particularly represent following automobile industry development direction is to be power with the hydrogen energy source, and fuel cell becomes optimal selection.
Fuel cell also more and more is being subject to people's attention aspect the marine communication means such as boats and ships.It is reported title: one 100 horsepower internal combustion engine is that powered ship is exercised the smog that was discharged in one day and is equivalent to 1 automobile and exercises 100,000 miles amount of smoke that discharged.Therefore, the internal combustion engine boats and ships also can not be ignored the pollution of water body, and the vehicles as individual speedboat, and its noise is also very big.In some rivers and lakes and some landscape nature reserve areas; people are in order to protect the biological environment of water body; alleviate the pollution to water body of refuse that power vessels such as gasoline, diesel oil discharge, the yacht boats and ships etc. that with the fuel oil are power are more and more by the system by power is substituted with the electricity.To some zones, some landscape excursion districts especially, relevant department cancel all before the ship power system, and adopt eco-friendly cell power systems.Traditional battery such as lead-acid battery are heavier, and volume ratio is bigger, shortcomings such as charging difficulty.Fuel cell changes into the device of electric energy as chemical energy, with advantageous feature such as its room temperature startup, transformation efficiency height, specific power density height, product zero pollutions, will win in these cell power systems, and is developed greatly.
The utility model content
The purpose of this utility model exactly in order to overcome the deficiency that above-mentioned prior art exists, provides a kind of fuel cell power generating system that marine communication means such as boats and ships uses that is particularly suitable for.
To achieve these goals, the utility model has adopted following technical scheme: a kind of fuel cell power generating system, comprise fuel cell pack, hydrogen gas tank, oxygen supply blower fan, hydrogen recycle pump, circulating water pump, heat exchanger, cooling water pump, control circuit board and storage battery, heat exchanger comprises water tank and is arranged on the interior fin of water tank;
Above-mentioned each equipment passes through pipeline or/and transmission line links to each other, wherein, the outlet of hydrogen gas tank connects the hydrogen inlet of fuel cell pack, the air outlet of oxygen supply blower fan connects the air intlet of fuel cell pack, the import and export of hydrogen recycle pump connect the hydrogen exit port of fuel cell pack respectively, the circulating water intake of circulating water pump connects the coolant outlet of fuel cell pack, the circulating water outlet of circulating water pump connects the circulating water intake of fin, the circulating water outlet of fin connects the cooling water inlet of fuel cell pack, the external water source of the cooling water inlet of cooling water pump, the coolant outlet of cooling water pump connects the cooling water inlet of water tank, the coolant outlet of water tank and environmental communication, control circuit board are connected the power delivery that fuel cell pack is produced by transmission line respectively and arrive storage battery with fuel cell pack and storage battery.
Described oxygen supply blower fan, hydrogen recycle pump, circulating water pump and cooling water pump also are connected by storage battery with control circuit board by transmission line respectively provides electric power.
Compare with the fuel cell power generating system of routine, the utlity model has following characteristics and advantage:
The operating temperature of the utility model fuel cell pack is preferably between 35 ℃～50 ℃ generally at 30 ℃～55 ℃.Generally speaking, the operating temperature of on-vehicle fuel heap is between 60 ℃～85 ℃, this mainly is because the heat radiation of battery, because for big fuel cell power generating system, the heat that fuel cell produces is many, main coolant such as the water of leaning on is taken the heat in the fuel cell pack out of, arrives then on the fin, utilizes outside air that the heat that accumulates on the fin is dissipated.Because the thermal transmission coefficient of air is smaller, thereby this mode heat-sinking capability is limited.If keep the lower operating temperature of whole system, and the fin that needs are very big, this will increase system bulk undoubtedly.A large amount of research is verified: battery pile is moved stability and the life-span that will improve fuel cell system greatly under lower temperature.Therefore, the operating temperature of reduction fuel cell pack also is to improve a kind of extraordinary method of fuel battery service life.
Fuel cell power generating system of the present utility model, the heat on its fin are mainly taken away by acyclic cooling water.Because the cooling effectiveness of acyclic cooling water is much higher than air cooling efficient, fin does not need significant volume just can guarantee that fuel cell produces in time dissipating of heat.That guarantees that fuel cell pack can be stable operates between 10 ℃～60 ℃.The battery pile operating temperature is lower, thereby the battery operation life-span significantly increases.
For the large-scale fuel cell power generating system of routine, because its operating temperature is than higher, battery is under than higher temperature, and the electrode dehydration is serious, and electrode becomes dry, decreased performance.Thereby this need carry out humidification to cell reaction gas, thereby integral battery door systematic comparison complexity.Fuel cell power generating system operating temperature of the present utility model is lower, and its reacting gas comprises that hydrogen and air partly needn't carry out humidification, directly the fueling battery pile.This simplifies the structure greatly, has reduced cost.
