Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a fuel cell extrusion alarm protection box. Background Art

[0002] A fuel cell is an energy conversion device that converts the chemical energy stored in the fuel and oxidant directly into electrical energy isothermally according to the electrochemical principle, so the actual process is a redox reaction. A fuel cell is mainly composed of four parts, namely the anode, cathode, electrolyte and external circuit. The fuel gas and oxidant gas are introduced from the anode and cathode of the fuel cell respectively. The fuel gas releases electrons at the anode, which are conducted to the cathode through the external circuit and combined with the oxidant to form ions. Under the action of the electric field, the ions migrate to the anode through the electrolyte and react with the fuel gas to form a circuit to generate current.

[0003] In order to protect the fuel cell from extrusion, a protective box is generally installed on the outside. However, the current protective box only has a protective function and does not have an alarm function. It cannot provide an early warning in the event of a collision, which makes the fuel cell at risk of spontaneous combustion, threatening the safety of the driver. Utility Model Content
