Military & Aerospace

The Military & Aerospace Team within Proton Energy Systems designs, develops, models and builds technology solutions based on our core proton exchange membrane (PEM) technology. We meet the technical needs of a diverse customer base that includes civilian and military government agencies and commercial aerospace partners.

The primary needs that Proton Energy Systems fulfills for our customers are supplying lightweight energy storage systems, hydrogen gas for fuel, or oxygen gas for breathing or as an oxidizing agent. We meet these needs by applying our high pressure water-electrolysis cells and high specific energy regenerative fuel cell (RFC) energy storage systems. An RFC decouples energy storage from energy conversion, which frees the RFC from the size and weight penalties of batteries. We have capability with unitized and discrete RFC energy storage systems to optimize mass, volume, and roundtrip efficiency for a variety of mission scenarios.
