JAXA Research and Development Report: Research reports on high altitude balloons
Proton exchange membrane fuel cells (PEMFCs), which generate electrical energy as long as they are supplied with fuels and oxidants, have been receiving significant attentions so that they offer higher specific energy densities than existing battery technologies in high-energy applications. We had been developing a 100 W-class fuel cell system that keeps electrolyte membrane well-hydrated without external humidification and can operate stably even under low pressure condition. The system aiming for super-pressure balloons had been tested emulating stratospheric conditions. Based on the previous works, the demonstration flight using the large balloon equipping the fuel cell system was launched to verify its performance in a practical high-altitude environment.
