[Asia Economy Reporter Ki-min Lee] POSCO International announced on the 8th that its subsidiary POSCO SPS plans to increase the production capacity of hydrogen fuel cell bipolar plates from the current 1,400 tons to about 10,000 tons by 2027.


Hydrogen fuel cell bipolar plates are a key component of hydrogen fuel cell stacks. A stack is assembled by laminating hundreds of unit cells, each consisting of an anode and a cathode. The bipolar plate serves as a channel supplying hydrogen to the anode and oxygen to the cathode, and also functions as a support between cells.


POSCO International explained that the hydrogen fuel cell bipolar plate 'Poss470FC' produced by POSCO SPS uses POSCO's highly conductive stainless steel material, which offers superior corrosion resistance, conductivity, durability, and uniformity compared to other materials. Previously, since 2006, POSCO Group has been developing metal bipolar plates for hydrogen electric vehicles through POSCO Technical Research Laboratories, and since 2018, POSCO SPS has started producing ultra-thin sheets for bipolar plates.


The bipolar plates produced by POSCO SPS are expected to be used not only in hydrogen electric vehicles and drones but also to expand into future fields such as robotics and Urban Air Mobility (UAM). According to McKinsey data, the global hydrogen economy market size is projected to reach 2,940 trillion KRW by 2050, with the number of hydrogen electric vehicles reaching 400 million passenger cars and 20 million trucks and buses.



POSCO International plans to invest in new facilities and expand its workforce to increase production capacity in line with the rapidly growing eco-friendly vehicle market. Jeong Hae-ik, head of the STS Business Division at POSCO SPS, said, "As new hydrogen electric vehicle models are increasingly launched, demand for 'Poss470FC' material is expected to surge. We will strengthen our position in the hydrogen electric vehicle parts market with POSCO SPS's precise ultra-thin rolling technology."
