Our fifth-generation hydrogen fuel cell has been successfully developed and put into the sale. Compared with the fourth generation, the fifth generation hydrogen fuel cell has made progress in volume and weight. At the same time, our new controller has entered the debugging stage and will be put into use after successful debugging. The use of the new generation controller will make our stack have more room for development, we will be able to get more power through a parallel connection, please look forward to it!https://www.bch-hydrogen.com/product/
