SEOUL -- Posco SPS, a unit of South Korea's steel group POSCO, will boost the production of its stainless steel separator from the current capacity of 1,400 tons to 10,000 tons by 2027 that can be supplied to 250,000 hydrogen-powered vehicles. The separator is a key component of fuel cell stacks.

An electric vehicle battery is designed in a structure where multiple units of cells are connected in series within a single cell-stack. The separator provides a channel for oxygen and air, connects electricity created at each cell and provides mechanical support. Posco SPS, a subsidiary of POSCO International, has produced Poss470FC, a stainless steel bipolar separator that contains chromium, defying rust and featuring high conductivity.

The stainless steel separator is applied to hydrogen fuel cells for drones and electric vehicles. POSCO International said in a statement on March 8 that the separator can be used in mobility industries including urban air mobility, which is an ecosystem covering personal air vehicles. POSCO SPS aims to expand its global market share in drive motor cores.
