Description
Technical field
The invention belongs to renewable energy utilization and Hydrogen Technology field, refer in particular to the solar cell water electrolysis hydrogen production technology of utilizing.
Background technology
Perhaps, fossil energy is that God vouchsafes human present, and exploitation and simple processing back just can be used.After yet these presents used up, the mankind just had to consider to use those not renewable energy sources so easily.Renewable energy source aboundresources such as sun power, wind energy, small power station, tidal energy, Geothermal energy, environmental friendliness, inexhaustible, however its shortcoming is also very obvious: energy density is low, and unstable is strong, utilizes the cost height.Utilize renewable energy power generation, supply of electric power cuts in and out, the time little when big, use very inconvenient, must be through the energy adjustment of peak load shifting.Present small-scale renewable energy power generation can be connected to the grid, and its unstable is flooded by the huge capacity of electrical network, can not manifest its disadvantageous effect.Yet, if large-scale utilization renewable energy power generation from now on will bring a large-scale electric power peak load shifting difficult problem.Though existing at present multiple electric power storing technology is under study for action, for example Caes, pump water energy-accumulating power station, store battery, liquid flow energy storage battery, super capacitor or the like, however the accumulate of electrical network scale remains a big technical barrier.Under the pressure of such pressure, scientist has found another technological approaches, utilizes hydrogen as secondary energy, becomes the strong of electric energy and replenishes, and is called Hydrogen Energy.During power surplus, can prepare hydrogen, be transported to the terminal user and use, also can store by brine electrolysis; During power shortage, can utilize hydrogen gas generation, replenish electricity needs.Hydrogen Energy also can become the secondary energy parallel with electric energy, utilizes unsettled renewable energy source to prepare Hydrogen Energy, and storage and transmission pipeline network by hydrogen come peak regulation.The conveying peak regulation of the gas energy is much simpler than the peaking problem of electric power, has just obtained good application in the Sweet natural gas West-East National Gas Transmission Project of China.So as effective renewable energy source carrier, Hydrogen Energy should obtain synchronized development with renewable energy source.
Utilizing sun power and wind power generation water electrolysis hydrogen production is the more hydrogen production process of two kinds of researchs, and the discontinuity of wind energy is stronger than sun power, and control is got up more complicated.It is multiple to utilize the technology of solar hydrogen making to have, and comprises solar energy hydrogen production by water decomposition, solar heat hydrogen production by water decomposition etc., substantially all is in the fundamental research stage, from practicability very long distance is arranged still.The solar cell water electrolysis hydrogen production is a kind of relatively renewable energy source hydrogen producing technology of reality, though still face the high difficulty of hydrogen manufacturing cost at present, technology maturity can accomplish that certain scale carries out industrial production.Need at present further to reduce system complexity, improve solar hydrogen making efficient, reduce system cost etc.Can estimate that in the near future, solar cell water electrolysis hydrogen production technology will become a kind of important technology of hydrogen gas production and be used widely.
Utilize in the solar cell water electrolysis hydrogen production technology, the matching problem between the generating capacity of solar cell and the electrolyzer capacity is the problem of a key.In order to reach maximum efficiency, the capacity of electrolyzer should be fit to consume all energy that solar panel produces.But the generated energy of solar cell changes along with intensity of solar radiation, and the maximum generation power of solar cell changes along with yield of radiation.To utilize sun power to a greater extent, need carry out power match solar cell and electrolyzer.This coupling be divided into grid type with from two kinds on net type, as shown in Figure 1.For the grid type water electrolysis hydrogen production system as shown in Fig. 1 a, multiple mode of connection such as the positive regeeration of also being incorporated into the power networks, the reverse feedback of being incorporated into the power networks, can by electrical network come the balance solar electrical energy generation unstable (Solar Energy, 2005,78:661-669).For shown in Fig. 1 b from net type sun power electrolysis hydrogen generating system, need carry out power match so that electrolyzer can effectively move.A kind of fairly simple power matching method is to be slightly little electrolyzer of power ratio solar cell peak power of solar cell coupling, is equipped with store battery again and carries out the energy storage.Utilize a part of solar electric power to carry out electrolysis when solar cell power is superfluous, remainder carries out battery charge; Carrying out power by store battery during the solar cell underproof replenishes.For example in the disclosed solar hydrogen-system making of U.S. Pat 20060088739A1, come the balance solar-electricity by charging and discharging of accumulator.Though this power match mode simple possible needs store battery in the system, increased the complicacy of system, has improved cost.And the life-span of store battery is maximum at present problem, generally has only hundreds of circulations, and this has limited the practicability in the sun power electrolysis hydrogen generating system greatly.
Directly solar cell is linked to each other with the electrolyzer that capacity is fit to, can use the flux matched battery system of energy, help reducing system complexity and cost.Arriaga etc. (Int.J.Hydrogen Energy, 2007,32:2247-2252) just with the solar cell of 2.7kW with one to have 25 single ponds, total power consumption be that the PEM electrolyzer of 5.6kW directly links to each other, it is 600 ~ 800W/m that the result is presented at radiating capacity
2In the time of in the scope, can realize power match preferably between electrolyzer and the solar cell, the working point is near the maximum power point of solar cell.Shown in Figure 2 is the solar cell working curve of this system and the working curve of electrolyzer.Can see, when solar radiant energy is low, the matching variation between electrolyzer and the solar cell, this can cause a big chunk sun power can't obtain utilizing, and causes system efficiency lower.
Directly electrolyzer is linked to each other with solar cell and also can bring other problem.When solar cell power was very little, the amounts of hydrogen of generation was even less than the infiltration capacity of gas permeation dielectric film, and this can cause the mixing of hydrogen and oxygen in electrolyzer inside, brings potential safety hazard.For high-pressure system, the infiltration capacity of hydrogen is bigger especially.Simultaneously, when directly linking to each other, owing to the instability of sun power, can bring the heat management problems of electrolyzer, electrolytic efficiency reduced when electrolyzer was operated below the design power scope.
The solar cell of research system optimization directly and the electrolyzer interconnection technique be the new direction of development of solar cell electrolytic hydrogen production technology, can either simplify hydrogen generating system, can improve the hydrogen production efficiency of system again.Up-to-date bibliographical information (Int.J.Hydrogen Energy, 2008,33:490-498), adopt by the series-parallel system of change solar battery group and the series-parallel system of electrolyzer group, can make working curve left and right sides translation in current-voltage relation figure of electrolyzer, to reach the purpose that is complementary with the solar maximum power curve.Shown in Fig. 3 is the working curve that obtains by the series-parallel system that changes solar battery group and electrolyzer group in the system of this article report.The series-parallel system of the PEM electrolyzer group by changing 4 groups of 75W solar cells and 5 groups of 50W makes the total energy transformation efficiency can reach 95%.By this method optimization, solar cell directly is connected with the PEM electrolyzer can improve hydrogen production efficiency, but this optimal way is not ideal enough, and the change of control series-parallel system is not easy to realize in the real system.
