Fuel Cell Graphite Bipolar Plate

Harog Technology has applied for more than 70 related patents in the field of fuel cells. The ultra-thin graphite bipolar plate for vehicles has a web thickness of 0.3mm, resistant to high temperature, high pressure and strong acid, service life >30,000h. Besides, we have air-cooled graphite bipolar plates for low-power products, which are currently being used in drones, two-wheelers, forklifts and other scenarios.
