Description

A kind of on-the-spot hydrogen manufacturing integrated fuel battery standby power system
Technical field
The utility model relates to stand-by power supply, relates in particular to a kind of on-the-spot hydrogen manufacturing integrated fuel battery standby power system.
Background technology
Fuel cell can be used in bank as stand-by power supply, hospital, the airport, business premises etc. substitute lead-acid battery and the diesel engine generator widely applied at present, have environment friendly and pollution-free, noiselessness, light, be convenient to many advantages such as maintenance.
Stand-by power supply is as improving constantly along with people's quality of the life, the fast development of society's suitability for industrialized production, modern society and economy have reached indispensable degree to the dependence of electric power, and electric power has become the master switch of society and economical operation, do not had electricity, all just are absorbed in comprehensive paralysis rapidly.
On communication base station, in case grid power blackout, stand-by power supply normally plays the uninterrupted power supply important function for ensureing communication.
At present, good more important occasion, in communication, stand-by power supply mainly adopts lead accumulator and the combined mode of diesel generating set to carry out, the present situation of this stand-by power supply is increasing with the contradiction between the demand of current stand-by power supply, mainly show: a. lead accumulator finite capacity, it is 10 hours that the standby time generally is no more than, and does not satisfy great emergent dangerous situation demand at all.B. and lead accumulator exist weight big, in the life-span short (about general 3-5), pollute big, streaking one, life-span be cannot say for sure shortcoming .c. such as card in order to prolong the generating standby time, be equipped with a large amount of diesel generation oil locomotives, generally is that the base station about 10-20 is equipped with an oily locomotive of generating.Most of the time, oily locomotive seal up for safekeeping need not, often need not be bad to oily locomotive, need often to safeguard that regular maintenance is more frequent that workload is big.When running into large-area power-cuts or great dangerous situation, oily locomotive is not enough.
Fuel cell is as a kind of generating equipment of energy-conserving and environment-protective, and volume is little, and is in light weight, noiselessness, low price, safeguard low, but characteristics such as continuous operation are suitable for use in the stand-by power supply field very much.Compare with diesel engine generator with lead-acid battery, have zero and pollute, environmental protection, characteristics such as integrated cost is cheaper.
Fuel cell can provide the non-firm power of ultra-long time as stand-by power supply, and increases with low costly, and this is the advantage place that fuel cell has cost competitiveness very much.
Need hydrogen during fuel cell operation, fuel cell wants for a long time operation continuously that a large amount of hydrogen of deposit must be arranged at the operation scene.The mode that obtains standby hydrogen has a variety of, and for example the mode of dispensing is dispensed into on-the-spot mode of installing then with hydrogen from hydrogen manufacturing factory.Because hydrogen manufacturing factory quantity is less relatively, the use hydrogen of Fen Saning especially relatively is not occasion very easily in traffic, and it is very uneconomical that this mode becomes, and its commercial operation difficulty is bigger, is difficult to find appropriate provider either.So this scheme has directly influenced the commercialization process of hydrogen reserve battery.In addition, hydrogen can in situ preparation, the mode of storage.The mode of on-the-spot hydrogen manufacturing is many.Such as preparing hydrogen by reforming methanol, methane reforming hydrogen manufacturing.This mode will obtain the high hydrogen system complexity of comparison purity, and the start-up time of generation hydrogen is long, and system complex is not for very suitable as the system of this response of will powering fast of stand-by power supply.The mode that also has a kind of on-the-spot hydrogen manufacturing in addition is the mode of brine electrolysis, and this mode need expend certain electric power.Reserve battery (lead-acid battery) generally is connected in parallel in the electric power system as auxiliary power, generally, has civil power in the system, so reserve battery does not provide electric power to load.When civil power cuts off the power supply, be connected in parallel on reserve battery in the system and start working and provide electric power for power consumption equipment.When civil power came, civil power provided reserve battery (lead-acid battery) charging power on the one hand by behind the AC/DC, provides electric power to load on the one hand.
If on-the-spot electrolytic hydrogen production is adopted in the hydrogen of fuel cell source, will consume certain electric weight like this.Will consume excessive electric power if the electrolytic cell outfit is unreasonable, so we need also further be equipped with AC/DC or overall electric distribution power consumption to original system.This scheme of electric power for original whole system can change bigger, drops into greatlyyer, in conditional this scheme of occasion of some power supply ability difficulty is passed through.System power dissipation can most of (even all) substitute lead-acid battery for electric power supply system of fuel cell, can reduce the AC/DC Switching Power Supply power in the original system behind the original system installation electric power supply system of fuel cell.If our reasonable disposition electrolytic cell, with being not more than of being equipped with of electrolytic cell or near in original whole system to the power of lead-acid battery charging, the whole system distribution will no longer increase power consumption, need not increase original distribution configuration, need not increase original electrical network burden, realize of the butt joint of a kind of gapless with original scene.Though hydrogen energy conversion efficiency in the whole process of preparation generating is lower than lead-acid battery, but fuel cell is as a non-firm power system, the running time of non-firm power is shorter, therefore the consumption rate of hydrogen is less, under most of state, hydrogen fuel cell is different from lead-acid battery, do not need floating current, do not need standby energy consumption, generally speaking, in whole hydrogen production-storage-power generation process, with needing the floating charge lead-acid battery to compare for a long time, energy consumption does not increase generally speaking, just can not improve the energy consumption of whole system.But fuel cell is as a kind of electricity generation system that non-firm power can be provided for a long time, and its marginal capacity is very strong.
