Platinum-Coated Titanium Plates
High-temperature sintering platinum coating is a process that forms a stably adhered platinum layer on the surface of titanium bipolar plates by treating a platinum solution at high temperatures. Leveraging the excellent catalytic performance of platinum, this process significantly enhances the electrochemical activity of bipolar plates. During the sintering process, temperature and time are precisely controlled to ensure coating uniformity and adhesion.
