Aircraft re-equipment for hydrogen fuel cell

Project concept

Forecasting that a suitable lithium battery technology could emerge in 15 years, the HDT team began to focus on the development of hydrogen fuel cells specifically designed to retrofit existing aircraft aids. To be light and stable, the structure must be air-cooled, so liquid-cooled fuel cells that work well in the automotive world, but due to the accompanying coolant tanks and pumps add extra mass that literally prevents you from going up to the skies. ...
Modern air-cooled fuel cells have limited power and service life and only operate at temperatures between -5 and +30 ° C.
Therefore, the HDT team decided to develop a forced air fuel cell that allows the fuel cell to cool down and increase its power.
We increase the power of the fuel cell stack by placing it in an air duct, where fans push under pressure, humidify and thermo-stabilize the air supplied to the hydrogen combustion chamber.

The advantage of this technology.

The supplemental oxygen supplied to the cathode of the fuel cell stack, combined with the new high temperature proton exchange membrane (HDTEMP) technology developed by Hydrogen Dynamics Technology, allows the fuel cell to be supplied three times as much hydrogen than a conventional design, thus tripling its specific output power without adding any coolers. This, in turn, leads to a significant reduction in aircraft weight. With all the improvements, Hydrogen Dynamics Technology delivers 2,300 watts of power per kilogram, with the best liquid-cooled fuel cells delivering 150-800 W / kg and air-cooled fuel cells around 800 W / kg.
