Description
Technical field
The present invention relates to Solid Oxide Fuel Cell technical field, especially a kind of dismountable solid-oxide fuel cell stack.
Background technology
Solid Oxide Fuel Cell is a kind of high efficiency energy conversion device, has fuel tolerance wide, does not use noble metal catalyst, structure of whole solid state, the advantages such as the life-span is long, pollution-free.But its industrialization process is subject to the restriction of cost, and cause cost high major reason is that its high-temperature sealing structure causes pile non-dismountable, and monocell is inconvenient to test its chemical property before dress heap.This just proposes extremely harsh requirement to the consistency of monocell.Before the consistency of monocell does not reach perfection, in pile, the performance deficiency of certain a slice battery all may become the short slab restricting whole heap performance, and the damage of certain a slice battery is also just equal to scrapping of whole heap.From the angle reduced costs, it is very important for developing dismountable pile.
3 detachable pile designs can be found in search Chinese patent, wherein patent of invention CN101373843A is for the independent air inlet of every a slice battery, not only cause the complicated of gas delivery, and every sheet connecting plate is sufficiently thick, the welding of guarantee air inlet pipe, have impact on the volumetric power density of pile; Patent CN100449846C laterally offers air inlet/outlet on every sheet connecting plate, and requires the specific position of battery soldering at connecting plate inside casing, not only processed complex, and connecting plate is also very thick, and pile is bulky; Patent CN1252844 arranges and seals multichip connection plate in plane framework, has complex structure, shortcoming that rate of finished products is low equally, and its pottery adopted to insulate to make framework processing very difficult.
Therefore the technology being badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of dismountable solid-oxide fuel cell stack.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of dismountable solid-oxide fuel cell stack, comprise base, negative end plate, positive end plate and element cell, described base two ends connect bottom negative end plate and positive end plate respectively by sealing strip, described negative end plate is connected by thermal insulation board with positive end plate top, the element cell of multiple compression is provided with between described negative end plate and positive end plate, gas distribution plate is connected bottom described element cell, connection combustion zone, described element cell top, described element cell top is through thermal insulation board.
Described gas distribution plate is insulator, is provided with inlet plenum bottom described gas distribution plate, and described inlet plenum one end connects fuel inlet pipe.
Seal is provided with between described multiple element cell.
Described element cell comprises connecting plate, cover plate, battery and cathode current collector, and described connecting plate side connects cathode current collector, and described connecting plate opposite side connects cover plate, and described cover plate connects battery.
Adjacent two element cells are connected with battery terminal contact by cathode current collector.
The quantity of element cell can be increased and decreased as requested.
Described sealing strip and seal are insulator.
The invention has the beneficial effects as follows: 1, repetitive is detachable, greatly extend the pile life-span, reduce pile cost; 2, can assembled in parallel multi-disc battery in repetitive, both improved fuel availability; Compared to the pile of monolithic series connection, after multi-disc cell parallel, series connection can not cause whole heap electric current to interrupt at once, for the eliminating of fault gains time due to the fault of certain sheet battery again; 3, have open air structure, air circulation vapour lock is little, can save the own power consumption of stack system parts, improves system effectiveness.4, exhaust combustion and cell power generation are combined, have compact conformation, heat energy is convenient to the advantage effectively utilized; 5, for traditional laminated type pile, each unit is not by the impact of other unit deadweight, and force environment uniform, controllable, contributes to improving the pile life-span.
