Description
Technical field
Electricity generation system is reformed by the multistage of fuel cell hydrogen source of liquid fuel the present invention relates to a kind of, belongs to the energy, again
Whole hydrogen manufacturing and efficiency power generation technical field.
Background technique
SOFC (solid oxide fuel cell) is using oxonium ion/proton conductor as electrolyte, work in relatively-high temperature
The fuel cell of (450~1000 DEG C), byproduct are the vapor of high quality, and UTILIZATION OF VESIDUAL HEAT IN value is high, electric-thermal combined cycle
Efficiency can be converted and be increased to 80%, hardly discharge any nitrogen oxides and oxysulfide.SOFC has technology power etc.
Grade is big, modularization power generation characteristics, can loading capacity according to actual needs configure SOFC module, meet different power grade need
It asks.Compared with the electric mode of tradition based on burning, SOFC technology significantly reduces the energy loss of fossil fuel and right
The destruction of ecological environment；From used Proton Exchange Membrane Fuel Cells (PEMFC) different for the device of power in the past, SOFC have work
The feature that activating catalytic ability is strong under the conditions of work, fuel range of choice is wide, noble metal electrode material can only be used by avoiding PEMFC
The limitation of (such as Pt) eliminates CO and poisons to electrode, and fuel is no longer limited to high-purity hydrogen.In addition, hydrogen container
Pressure will usually accomplish 70Mpa or more, and pressure is higher, and filling process energy loss is bigger, and spillage risk is also bigger.Using SOFC
The security risk that not only can be stored to avoid high pressure hydrogen, occur in transport can also avoid being reduced and being carried using high pressure tank
Weight power, to increase the flexibility of fuel selection, storage and transport.Since SOFC power density is high, system specific power can
To reach 300Wh/kg, pile specific power reaches 3kW/L, compared with carrying the PEMFC dynamical system that high-purity hydrogen is fuel,
Effective power density after deducting fuel cell system own wt can be improved 2 times, and alternate-engine the main direction of development is
At high speed, low oil consumption, ultra high efficiency and ultra-clean, therefore SOFC can be used as to the electrical source of power of engine.
SOFC is structure of whole solid state, and there is no the leakage of the burn into of liquid electrolyte and pollution problems, to the purity of carbon fuel
It is required that it is lower, and convenient for using for reference existing combustion apparatus, solve the problems, such as fuel continuous-feeding, therefore by the wide of domestic and international researcher
General concern.Researcher starts from the sixties in last century to the research for the SOFC that hydrocarbon is fuel, quickly grows after the nineties,
The U.S. has obtained interim progress in the field, completes the testing research of laboratory level compact battery or battery pile.Using
Hydrocarbon include natural gas, coal gas, biomass gas, diesel oil and other hydrocarbons.With gaseous state nytron
Object is that the SOFC of fuel has many advantages, is not required to complicated external reformer unit；It is combustion with liquid fuel and solid-state coal dust
The SOFC of material generally requires external reformer unit, to meet the stability that SOFC works long hours.SOFC is used as automobile, ship
And aircraft etc. hybrid power power supply when, it is contemplated that use the consistency and fuel storage and fortune of fuel with all kinds of engines
Defeated flexibility, liquid fuel become first choice.
As the power source of system, it is necessary to have the adaptations of high reliability, concealment, high-energy density and environment
Property.I.e. under the supply of limited fuel, the electric power safeguard of longer time is provided.In view of the energy per volume of liquid fuel is close
The advantages that degree is big, transport is convenient, the liquid hydrocarbons such as methanol, ethyl alcohol are common portable fuel goods and materials.But they are
The carbon liquid material of opposite low energy source density, by taking the reaction of the vapor reforming hydrogen production of kerosene as an example, density ≈ 0.8g/cm3, average
Molecular formula=C12H24, maximum hydrogen output is 0.34g-H2/mLKerosene(C12H24+24H2O→12CO2+36H2)；And methanol and ethyl alcohol
Maximum hydrogen output be respectively 0.14g-H2/mLMethanolAnd 0.21g-H2/mLEthyl alcohol(CH3OH+H2O→CO2+3H2；C2H6+3H2O→
2CO2+6H2)。
Compared with kerosene, gasoline-range is lower, inflammable and explosive, and the raw material as vapor reforming hydrogen production has larger difficulty
(steam reforming reaction is mostly strong endothermic reaction, and the combustion reaction of equal fuel need to be generally coupled as supplying heat source.And gasoline fires
The poor controllability of burning).The carbon number distribution of diesel oil is wider than kerosene, and composition is more complicated, during vapor reforming hydrogen production
Catalyst is easier to poisoning decaying.And the flammability of diesel oil is also easy to produce a large amount of black smoke particulate matters in burning also below kerosene, blocks
React pipeline.Thus, in the current state-of-the-art, kerosene have concealment it is good, it is reliable for operation, highly-safe, power generation effect
The advantages that rate is high and mobility is preferable, it is considered to be the selection of fuel cell hydrogen source the most feasible in three kinds of oil products.
