Especially in the range of 1800-2000 ℃, SiC has good ablation resistance. Therefore, it has broad application prospects in aerospace, weapon equipment and ...

Working principle and advantages of hydrogen fuel cell stack

by admin on 22-02-12

Fuel cell is a kind of energy conversion device, which can convert the electrochemical energy of fuel into electrical energy. It is called fuel cell because it is an electrochemical power generation device together with the battery. A fuel cell that uses hydrogen as fuel is a hydrogen fuel cell. ...

vanadium battery system(VRFB VRB)

by admin on 22-01-24

As the place where the reaction occurs, the vanadium stack is separated from the storage tank for storing the electrolyte, which fundamentally overcomes the self-discharge phenomenon of traditional batteries. The power only depends on the size of the stack, and the capacity only depends on the el...
