3. Department applicants open patent reading
3.1 Hongtian Company
In October 2020, Hongtian Company published a total of 92 patents in the fuel battery field, including important technical branches such as electric reactors, system control, and whole vehicles.
The patent number of the Hongtian company’s fuel battery related specialties analyzed below is JP2020177737A and JP2020173973A. JP2020177737A and JP2020173973A both touch and metal double plate.
3.1.1 JP2020177737A, JP2020173973A——Fuel Battery Metal Double Elbow Plate
The metal double plate acts as a support membrane electrode and a reaction gas seal in the fuel cell system, and the sealing function of the metal double plate is particularly important. Today, the important thing for metal double plate sealing is to install protruding ribs on the metal double plate, and the height of the ribs are sealed by Sugar baby adhesive or welding. However, during the application of fuel batteries, the pressure energy over a long period of ti TC:
