Problems solved by technology

However, the introduction of balance tubes, on the one hand, has great technical difficulties for small and shaped fuel tanks that require non-directional use; on the other hand, it will cause leakage of liquid fuel, which will cause safety problems
Currently, there is no technology to achieve a leak-free, non-directional fuel tank in a fuel cell

Abstract

A leak-free and non-directional fuel tank for fuel cells comprises a tank body, an inner container and a joint. The tank body supports and protects the inner container, and is in sealing connection with the inner container at the outlet of the tank body. The inner container contains fuel, and is made of an elastic material or a flexible film material. The inner container has the capability of variable volume, and is used to ensure the air pressure balance between inside and outside when the internal fuel increases or decreases. The joint is an interface which has the function of a stop valve and is used to connect the fuel chamber of the inner container with an external pipeline.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel tank for non-leakage and non-directional fuel cells. It is suitable for microgravity operating environments or occasions with high requirements for fuel tank liquid leakage. Background technique [0002] A fuel cell is a chemical reaction device that directly converts chemical energy in fuel into electrical energy. The fuel cell is not limited by the Carnot cycle, and has the characteristics of far greater efficiency than the internal combustion engine, and the reaction products are mainly water and carbon dioxide. It is an environmentally friendly green energy source and is considered to be an ideal power generation device in the future. Aerospace and other aspects have broad application prospects. [0003] A liquid fuel cell is a power generation device using liquid fuel, typically a direct methanol fuel cell (DMFC). Compared with the gas-fed fuel cell system (hydrogen-oxyge...
