The right choice for safe and eco-friendly vehicles
Built on POSCO¡¯s GIGA STEEL and electric steel sheets as well as POSCO Chemical¡¯s
cathodes and anodes, we provide solutions for safer and lighter automobiles.
Hydrogen Fuel Cell
This is a device designed to generate electricity continuously through a reaction between hydrogen and oxygen. Consisting of stacked cells, it serves as the engine for a fuel cell electric vehicle.
The bipolar separator provides a channel for oxygen and air, connects electricity created at each cell and provides mechanical support. For this application, stainless steel1) which can withstand harsh conditions is commonly used. Compared to graphite, which is expensive and vulnerable to impacts, POSCO¡¯s Poss470FC2) is reasonably priced, rigid and easy to form. Most of all, it contains chromium, thus defying rust and featuring high conductivity.
