In terms of the hydrogen fuel cell tramcar, the hydrogen fuel cell technology is used to generate electricity through the direct electrochemical reaction between hydrogen and oxygen.

A breakthrough has been made in a series of key technologies such as the fuel cell/supercapacitor hybrid traction and control, allowing to fully remove the pantograph and overhead contact system, filling the gap in this field, thus achieving the "zero emission" of pollutants and "network-free" operation in the whole process.
