Singapore based-Horizon Fuel Cell Technologies' Aeropak fuel cell is on display here (static BC-075). This fuel cell power system is to be evaluated in this and the next quarter by its manufacturer to prove its high-impact and 22,000ft (6500m) operational altitude capabilities.
Aeropak uses refillable dry-fuel cartridges that can provide 900Wh of power while weighing 2kg (4.4lb). Horizon Fuel Cell Technologies technology has been demonstrated with the test flights of the Hyfish 1kW fuel-cell-powered German Aerospace Centre DLR demonstrator and the Pterosoar unmanned air vehicle. For the Hyfish, Horizon Fuel Cell Technologies provided the cell stack.
The Pterosoar flew 128km (69nm) world record in 2007 in California using a Horizon fuel cell system.
