[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. It is also called an electrochemical generator. It is the fourth power generation technology after hydroelectric power generation, thermal power generation and atomic power generation. Fuel cells need to undergo high-temperature testing before mass production to verify their reliability.

[0003] The patent with application number CN202022263797.8 discloses a hydrogen fuel cell test box, including a test box body, a water outlet, a telescopic spring and a support plate. A limiting structure is arranged on one side of the interior of the installation slot. The limiting structure includes a handle, an adjustment rod, a limiting baffle, a connecting groove and an extrusion plate. The limiting baffle is fixed on the outer surface of the adjustment rod, and an extrusion plate is fixed on one side of the adjustment rod. The other side of the adjustment rod is fixed with a handle. By installing an extrusion plate on one side of the interior of the installation slot, the extrusion plate is in direct contact with the battery, and can directly contact with the battery to squeeze and fix the battery, thereby realizing the limiting fixation of batteries of different sizes.

[0059] It should be noted that: Fig.12 As shown, the flame heats the circulating curved pipe 506, so that the water flow in the circulating curved pipe 506 is heated and boiled and then flows upward.
