EH Group tests high-temperature PEM fuel cell to decarbonise aviation

EH Group has successfully tested its fuel cell technology in high-temperature PEM mode (HTPEMFC). Its unparalleled design flexibility regarding form-factor and size means that certain materials, such as the membrane, can be modified with relative ease to operate it in either LT or HT fuel cell mode.

More crucially, the performance edge achieved by the company in PEMFC appears replicable in HTPEMFC, too.

Preliminary testing on short stacks has delivered more than 2.3 kW/L of power at atmospheric pressure, thanks to the unique stack structure and design with <1mm cell pitch.

“It is extremely satisfying to see the validation of our cell structure as a platform technology. It opens up a whole new arena of development in HTPEMFC and new application potential,” said Mardit Matian, Founder of EH Group.

High-temperature PEM fuel cells offer the potential to decarbonize aviation for aircraft requiring power levels well beyond those of batteries and even LTPEM fuel cells. Additionally, they open up other significant market opportunities, such as in the maritime sector and stationary power.

“Whilst there is clearly some development work to be undertaken, this technology would be an ideal candidate for the maritime and aviation sectors, for example where hydrogen purity & thermal management challenges are more pronounced,” added Christopher Brandon, Co-Founder of EH Group.
