About this opportunity
Navy STTR topic — under DoW STTR 2026 BAA (Solicitation 26.TZ, Release 5) — Accepting submissions 2026-08-26 to 2026-09-23. Objective: Develop a rugged, reliable, efficient fuel cell system with a high power-to-weight ratio and incorporated intelligent control algorithms and feature modularity. Description: The Navy and Marine Corps are actively seeking to enhance the range, endurance, and payload capacity of their unmanned aircraft systems (UAS). In recent years, hydrogen fuel cells have emerged as a promising technology for propulsion and power systems that can improve UAS operational capabilities [Refs 1-4]. While various fuel cell types exist, proton exchange membrane (PEM) fuel cells are most prominently used for UAS applications [Refs 5-6]. However, further improvements to performanc...
