Description
Technical Field
The utility model relates to a fuel cell technical field especially relates to a fuel cell test equipment.
Background
A fuel cell is an electrochemical device that converts chemical energy of a fuel (e.g., hydrogen, etc.) into electrical energy. In practical applications, a fuel cell generally includes a stack formed by connecting hundreds of single cells in series. The performance of the stack will be affected by the assembly error of each unit cell.
Among them, the assembly pressure of the stack is one of important parameters affecting the performance of the fuel cell.
The assembly pressure value of the stack is too small, which may cause fuel leakage or generate too large contact resistance, thereby reducing the output power of the fuel cell.
The excessive assembly pressure value of the stack can cause the excessive pressure of each single battery to damage the membrane electrode assembly and even prevent the gas participating in the electrochemical reaction from passing through, thereby reducing the output power of the fuel cell.
During the test of the output power of the fuel cell, the assembly pressure is required to be applied to the electric pile so that the single cells are connected in series. In the prior art, one of the methods is to bind the galvanic pile by a steel belt binding mechanism so as to apply assembly pressure to the galvanic pile; the other type is that the end plates on two sides of the electric pile are clamped through a screw and nut locking mechanism so as to apply assembling pressure to the electric pile.
The method has the advantages that the assembly pressure of the galvanic pile is relieved in the prior art, and the method is very inconvenient. After the fuel cell is tested, a large amount of time is wasted by disassembling the steel band binding mechanism or the screw nut locking mechanism. Moreover, if the same fuel cell is observed and detected for a long time, parts such as steel strips and the like can be aged, so that the assembly pressure born by the galvanic pile is not in a normal range, and the detection result is inaccurate.

Specifically, the assembly pressure of the stack 10 is known by the pressure detection gauge 6. If the pressure value is too large, the upper pressure plate 5 is adjusted towards the direction far away from the galvanic pile 10 until the assembly pressure meets the requirement; if the pressure value is too small, the upper pressure plate 5 is adjusted towards the direction close to the galvanic pile 10 until the assembling pressure meets the requirement.
In the present embodiment, the lower platen 2 is provided with a fuel inlet joint 101, a fuel outlet joint 102, an air inlet joint 103, an air outlet joint 104, a coolant inlet joint, and a coolant outlet joint.
