Description
Technical field
Marine tidal-current energy electrolytic seawater technical field is the present invention relates to the use of, more particularly to a kind of marine tidal-current energy seawater hydrogen making
Oxygen unit.
Background technology
Expanding economy and the growth of population so that people are increasing to the demand of the energy.At present using oil, coal as
The fossil fuel of representative is still main energy sources.Due to the limited reserves of fossil fuel can not will meet it is growing
Energy demand and occur energy crisis at last, while the use of fossil fuel brings serious environmental pollution, is current climate
One of main inducing to warm.Therefore development cleaning, the requirement of reproducible new energy are more and more urgent.Hydrogen Energy is burnt because of it
Product is water, will not cause environmental pollution, has the advantages that cleaning, efficient, pollution-free and can store and transport.
Solar energy, wind energy, biomass energy and ocean energy etc., it is not only nexhaustible and also with cleaning, reproducible advantage,
The extensive concern of international community is received in recent years.However, these renewable resources all have intermittent and regional characteristic, currently
It is main using form be to generate electricity, its electric energy has respective particularity because of different-energy reformulationses.By taking wind energy as an example, it is not
The grid-connected impact to power network of stable electric power has turned into an outstanding problem of current wind energy utilization.Ocean energy (including marine tidal-current energy,
Tide energy etc.) also there is similar feature.After the conversion of these energy, the shortcomings that being not easy to store and transporting is respectively provided with.Hydrogen Energy is fired because of it
The product of burning is water, will not cause environmental pollution, has the advantages that cleaning, efficient, pollution-free and can store and transport, currently
It is considered as optimal energy carrier.
Water electrolysis hydrogen production is presently the most the widely used technology that renewable resource is converted to hydrogen.When two electrodes
(negative electrode and anode) leads to upper direct current respectively, and when being immersed in the water, in the presence of catalyst and direct current, hydrone is in sun
Pole loses electronics, is broken down into oxygen and hydrogen ion, and hydrogen ion reaches negative electrode by electrolyte and barrier film, generation is combined with electronics

Film.Because asbestos have carcinogenicity, many countries have prohibitted the use of.It is reported that the polymer such as PPS, PTFE, PSF have and
Characteristic as asbestos, or even it is also advantageous over asbestos, it would be possible to substitute asbestos and turn into the diaphragm material of alkaline electrolytic bath.Development
New electrode material, catalytic reaction efficiency is improved, be the effective way for improving cell efficiency.
Proton exchange membrane electrolysis cells turn into very promising device for producing hydrogen because conversion efficiency is very high.Due to using
Very thin solid electrolyte, there is good mechanical strength and chemical stability, and ohmic loss is smaller.PEM electricity
Groove efficiency is solved up to more than 90%.But due to PEM and platinum electrode catalyst is used, it is expensive, it is extensive to constrain its
Use.With the maturation of PEM cell technologies and the reduction of price, solid electrolyte may be by as the master of hydrogen manufacturing
Device.
Means of solid oxide electrolytic cell is a kind of emerging cell technologies.The shortcomings that this electrolytic cell is to be operated in high temperature,
Selection to material brings a definite limitation.Advantage is that higher reaction temperature causes in electrochemical reaction, and part electric energy is warm
