PowerUP Energy Technologies will develop a 1kW liquid-cooled closed cathode hydrogen fuel cell stack for the Lunar cargo ships – and it has inked a new contract with the European Space Agency for the effort.
The Estonia cleantech start-up today (August 2) formalised the news, stating that, as well as Lunar cargo ships, the hydrogen fuel cell stack could also be used for rovers.
In normal conditions, fuel cells are open cathode, however, due to the lack of oxygen on the moon and Mars, closed cathode fuel cells need to be used.
There have been several research and development activities on regenerative PEM fuel cell systems for space applications in the past decade.
