The report, ‘Polymer Fuel Cells – Cost reduction and market potential‘, published by the Carbon Trust, outlines how innovative UK companies are at the forefront of achieving breakthroughs in polymer fuel cells which could address cost, the main barrier to the wide scale deployment of polymer fuel cells.

The report, which was launched at the ‘Clean Tech investor Conference – Investing in Fuel Cells’ in London on 27 September 2012, states that a continued focus on technology innovation could make fuel cell cars cost competitive with internal combustion engine cars and lead to them forming a third of all vehicles on the road by 2050.

Polymer fuel cells operate at lower temperatures and are smaller and lighter than other fuel cells, making them more suitable for use in cars and vans.

Current state-of-the-art polymer fuel cells are predicted to cost $49 per kilowatt in automotive applications when manufactured at scale.

In order to be competitive with internal combustion engine vehicles, automotive fuel cells must reach a cost of approximately $36 per kilowatt according to a Carbon Trust cost analysis.

Cost savings can be achieved by reducing material costs (notably platinum use), while increasing power density, reducing system complexity and improving durability.

The Carbon Trust is supporting five UK organisations through its $10 million Polymer Fuel Cells Challenge to reduce the costs of polymer fuel cells.

ITM Power has developed a membrane with the potential to roughly double the power density of a cell.

Acal Energy has developed a liquid cathode with the potential to directly reduce platinum use by at least two thirds and eliminates the need for some standard components of a fuel cell.

Ilika specialises in developing new materials have developed a platinum free catalyst which, on a cost/performance basis, that has the potential to be 70% cheaper than the current industry standard.

Imperial College and University College London have developed a novel stackable cell architecture that uses low cost materials and manufacturing techniques with breakthrough potential in terms of cost reduction.

The report shows that reducing the cost to better than $36 per kW would lead to a dramatic market expansion with 200 million more fuel cell vehicles being deployed by 2050 taking the total to some 690 million fuel cell vehicles.

This would increase the value of the global fuel cell vehicle market by $30 billion to $261 billion a year by 2050 with the market in the UK worth some $4 billion a year.

It would also reduce global carbon emissions from vehicles by an additional 260 million tonnes per year by 2050 – equivalent to the current annual emissions of Taiwan.

James Wilde, Director of Innovation and Policy at the Carbon Trust, said “our new analysis shows that the future is bright but innovation is essential to unlock the market potential by driving down the costs of new polymer fuel cells.”

“The UK, through its leading companies, is in pole position to benefit from an expanded global market for fuel cell vehicles,” he said.

The Carbon Trust’s Polymer Fuel Cell Challenge is now in its second phase where organisations with potential breakthrough technologies that could achieve this step-change in cost are moving from feasibility testing towards commercial development with industry partners.
