Fuel-battery back welding process

A fuel battery return weld manufacture process that is how to weld the circuit groupware to the fuel battery double- electrode board, and also make the heat energy in the return weld manufacture process can not destroy the other groupware on the fuel battery double- electrode board (such as the film electrode group). The fuel battery double-pole board is with the first part and the second part, the first part is set at least one film electrode group, the second part is used for battery return weld manufacture process. The first step is: places at least one circuit groupware at the second part of the fuel battery double- electrode board. The second step is: puts the fuel battery double- electrode board that complete the first step in the protecting equipment in order that the first part of put fuel battery double- electrode board is covered by the protecting equipment, and the second part is not covered by the protecting equipment completely. The third step is: processes the return weld dispose for the fuel ba
