摘要:
Bipolar plates are vital elements of fuel cell vehicles which are expected to be a key technology for reducing CO2 emissions. They are required to have many functions and properties, such as acting as flow channels for fuel gas and acting as current collectors, also resisting corrosion, and possessing thinness for downsizing and lightening. Since several hundred bipolar plates are installed in each fuel cell vehicle, their productivity and cost reduction are also essential. Hence, Kobe Steel has developed nano-carbon composite-coated titanium (NC titanium), the world’s first pre-coated bipolar plate material that meets the above requirements. NC titanium is installed in vehicles such as the fuel cell vehicle MIRAI, which Toyota Motor Corporation launched in 2020. This paper explains the development concept, structure, and characteristics of NC titanium. © 2024 Kobe Steel Ltd. All rights reserved.
