Fuel cells (FC) is a technology that generate electricity from hydrogen, having only water as a byproduct, thus creating no local pollution. This technology, having a high conversion efficiency, and hydrogen, allowing renewable electricity storage, have a great potential to contribute to address energy challenges facing Europe. In particular they can allow renewable energy technology to be applied to transportation helping Europe to cope with the intermittent character of renewables such as wind power. Thus major automotive Original Equipment Manufacturers (OEM) are working on the technology and some production model of a fuel cell car have been announced to be introduced in 2015. 
However, from the automotive OEM’s point of view, two main targets are mandatory for the vitality of the fuel cell vehicle market :
The only way to reach these targets is to use metallic bipolar plate for automotive fuel cell stacks and most of the automotive OEM’s have already chosen this technological option.
FCH JU funded project Auto-Stack  aimed (in particular) to give a precise evaluation of the cost of each component of the PEMFC . The bipolar plate was also addressed during the project. The project showed that the effect of scale was strong at low production rate and decrease with high production rate. Raw materialsf or coating represents the main cost contributors of bipolar plates raw materials cost. Also the project report demonstrate that “Embossing” and “Coating” are the most expensive process steps at low production rate (1.000 vehicle a year) and that “Coating” step become the most costly step from 10.000 vehicle/year (mainly due to slow production rate and equipment cost)
That is why the COBRA project will focus its research on the improvement of the forming process and on the coating (new processes and new materials). COBRA will address the cost evaluation and optimisation of the bipolar plate production process. The cheapest production process will be selected (as the same level of bipolar plate performance) in order to reach the 2.5 €/kW cost target at high production rates. At intermediate production rates corresponding at the emerging markets in the earlier years of commercialisation, process options will be also evaluated in order to allow PEMFC to share significantly the electric automotive market.
