Background
A hydrogen fuel cell engine is a green power generation device that directly converts chemical energy into electrical energy by electrochemically reacting fuel hydrogen and oxidant oxygen. The process does not involve combustion, has no mechanical loss, does not need intermediate conversion of heat energy and mechanical energy (a generator), and has high energy conversion rate. The fuel cell is a power generation device, but is not discarded after being used up like a general non-rechargeable battery, and is not charged continuously like a rechargeable battery, and fuel is added continuously to maintain the power of the fuel cell when the fuel cell is used up, and the required fuel is 'hydrogen'. The product is only electricity, heat and water, not only has no pollution, but also avoids the problem of time consumption of the traditional battery charging, is a new energy mode with development prospect at present, and can obviously reduce air pollution and greenhouse effect if being popularized and applied to vehicles and other high-pollution power generation tools.
At present, the arrangement of the reactant and cooling water inlet and outlet of the fuel cell stack is compact, and the arrangement is not beneficial to independently arranging pipelines. In addition, in order to meet different power requirements, single fuel cell stacks need to be connected in series, and a stack design is often performed. This makes it more complicated to place the piping separately for each of the fuel, oxygen and cooling water chambers, and there is a non-uniformity in the flow of the liquid. The existing distributor is mostly welded and processed by adopting stainless steel materials, a plurality of distributors are piled, a plurality of branch flow channels are provided, the welding difficulty is high, the process is complex, and the integral air tightness after welding is difficult to ensure; the metal distributor is rigidly fastened with the cell stack by adopting screws, the mounting process is complex, and the precision requirement on the mounting hole of the flange plate is high.

Detailed Description
The present embodiment is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a novel fuel cell stack silica gel distributing pipe comprises a main cavity 1 and a plurality of shunt tubes 2, wherein the main cavity 1 and the shunt tubes 2 are integrally formed; shunt tubes 2 distribute on the lateral wall of the main cavity body 1, shunt tubes 2 one end opening one end and the main cavity body 1 intercommunication, main cavity body 1 one end opening one end is sealed, the distributing pipe adopts the silica gel material to make.
Wherein, every shunt tubes 2 links to each other with the runner pipe of the correspondence of every battery pile respectively, adopts the clamp fastening between shunt tubes 2 and the runner pipe, because distributing pipe 2 adopts the silica gel material to make, has certain flexibility, consequently allows to have certain error between distributing pipe 2 and its corresponding runner pipe. The fuel or cooling liquid flows in from the opening of the main cavity 1, passes through the shunt tubes 2 and then enters the cell stack connected with each shunt tube 2.
Preferably, the shunt tubes 2 are uniformly distributed on the main cavity 1, and the projections of the shunt tubes 2 on the vertical plane are located on a straight line. The open end of main cavity 1 communicates with fuel or coolant liquid feeding mechanism, and the vehicle is at the operation in-process, and fuel or coolant liquid are full of whole main cavity 1 all the time, and shunt tubes 2 pipe diameter is unanimous, and fuel or coolant liquid are in each shunt tubes 2 and the intercommunication port pressure of main cavity 1 unanimous basically, can make the even inflow of fuel or coolant liquid every cell stack, make the work efficiency of every cell stack keep the equilibrium as far as possible.
Preferably, the main cavity 2 is further provided with a temperature sensor mounting tube 3 for mounting a temperature sensor, so that the temperature of the fuel or the cooling liquid flowing through the main cavity can be detected in real time.
Preferably, the main cavity 1 is cylindrical, and the closed end thereof is spherical; the shunt pipe 2 is L-shaped.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
