Abstract
A kind of No leakage, non-directional fuel cell-use fuel tank, including tank body, liner and connector.Tank body plays support, protection liner, realizes and is tightly connected with liner at tank outlet.Liner plays a part of to contain fuel, is made of elastic material or flexible thin-film material.Liner has the ability of variable volume, for the air pressure balance inside guaranteeing when inner fuel increases or reduces with outside.Connector is a kind of interface for acting to connect liner fuel cavity and exterior line with shut-off valve function.
Description
Technical field
The present invention relates to fuel cell field, specifically a kind of No leakage, non-directional fuel cell-use fuel tank.
There is the occasion of high request suitable for microgravity running environment or to fuel tank liquid leakage amount.
Background technique
Fuel cell is a kind of chemical reaction equipment that the chemical energy in fuel is converted into electric energy.Fuel cell is not
It is limited, is had the characteristics that much larger than the efficiency of internal combustion engine, and reaction product is mainly water and carbon dioxide, is ring by Carnot cycle
The green energy resource of border close friend, it is considered to be the power generator of future ideality, traffic, communication, military affairs, in terms of have it is wide
Wealthy application prospect.
Fuel liquid battery is a kind of power generator using liquid fuel, typical such as direct methanol fuel cell
(DMFC).For the fuel cell system (hydrogen-oxygen fuel cell etc.) of gas feed, the combustion of liquid fuel cell system
Batch can generate vacuum at work, as fuel reduces inside, and it is difficult to will cause feed after vacuum reaches certain value.Cause
This, needs to realize air pressure balance with one section of balance pipe connection fuel tank inner cavity and outside atmosphere.But introduce balance pipe, a side
Face, for requiring have very big technical difficulty for non-directional small-sized, the special-shaped fuel tank used；On the other hand, it will cause
The leakage of liquid fuel, and then cause safety problem.Currently, there are no realize No leakage, non-directional fuel in fuel cell
The technology of tank.
Summary of the invention
A kind of No leakage, non-directional fuel cell-use fuel tank, including closed hollow rigid tank body 1,1 upper end of tank body
Liquid outlet 2 is offered, in the tubular liner 3 for being equipped with the closed flexible material or elastic material in a upper end opening lower end in tank body 1,
The inner wall airtight connection of 3 upper open end of liner and 1 top of tank body, and liquid outlet 2 is located at the area that 3 upper open end of liner is surrounded
In domain.
The connector 4 with shut-off valve function is equipped at liquid outlet 2 outside tank body 1.
1 bottom of tank body is equipped with air pressure balance mouth 5 as needed.
The material of the rigidity tank body is metal material or hard plastic material；
The flexible material or elastic material are plastics, rubber or waterproof cloth；
The elastic material is the films such as PE, PP.
The liquid outlet 2 of tank body is connect by pipeline with feed pump through valve.
Fuel tank of the invention is mainly made of tank body, liner and connector.
Outer tank body has some strength for protecting and support liner, may be selected according to use condition by metal, nonmetallic
Or composite material is made.
Liner and tank body realize sealed connection at tank outlet.
Liner storage inside fuel, no gas or only a small amount of gas exist.
Liner is made of the material of fuel-resistant corrosion and has certain intensity, and bullet may be selected in liner according to the needs of use
Property material and flexible thin-film material.
Connector is a kind of interface for acting to connect liner fuel cavity and exterior line with shut-off valve function.
According to use condition tank base may be selected in the program, and whether there are air pressure balance mouths to be communicated with the atmosphere.
The fuel tank can also be used for the storage of the buffer solution before certain fuel cell start-ups, such as DMFC system.
The invention has the advantages that and advantage
1. totally-enclosed design is used, in addition to joint can (quantity takes there are very low amount when using and being filling
Certainly in the selection of connector) fuel outside, realize the target of zero leakage；
2. either closed compression gas still connects open to atmosphere fuel tank, the deformability of liner make inner fuel not
In disconnected extraction process, avoids internal generation vacuum and cause fuel that can not continue to extract；
3. the feed purpose of any direction may be implemented.
Detailed description of the invention
Fig. 1 is one of structure composition figure of the invention；
Fig. 2 is the two of structure composition figure of the invention.
Specific embodiment
To further illustrate the present invention, following embodiment is enumerated.
A kind of No leakage, non-directional fuel cell-use fuel tank, equipped with closed hollow rigid tank body 1,1 upper end of tank body
Liquid outlet 2 is offered, in the tubular liner 3 for being equipped with the closed flexible material or elastic material in a upper end opening lower end in tank body 1,
The inner wall airtight connection of 3 upper open end of liner and 1 top of tank body, and liquid outlet 2 is located at the area that 3 upper open end of liner is surrounded
In domain.The connector 4 with shut-off valve function is equipped at liquid outlet 2 outside tank body 1.
The NS4D42002 model general-purpose interface of CPC brand and the NS4D17002 model general-purpose interface of pairing are connected,
NS4D17002 general-purpose interface end is connect with feed pump.External fuel is injected into fuel tank by the work of pump.It will
NS4D17002 model general-purpose interface is connect with the NS4D42002 model general-purpose interface on fuel cell, fuel battery inside fuel
Fuel supply can be realized in pump work.
The above is only a specific embodiment of the invention, but protection scope of the present invention is not limited in above
Hold.Variation, replacement based on presently disclosed technology should be covered by the protection scope of the present invention.
