Princeton Junction, New Jersey
Project Term:
01/01/2021 - 12/31/2022

Technology Description:

Fuceltech proposes to develop an innovative low-cost, lightweight Energy Storage and Power Generation (ESPG) system for commercial aircraft. Fuceltech will develop a monopolar wound single fuel cell potentially as high as 10 kW rating and a novel stacking approach to deliver hundreds of kWs of power from a single small and lightweight stack. Fuceltech will use ethanol as a fuel and a reformer that delivers extremely low CO concentration in the reformate to the fuel cell. In phase 1, Fuceltech will develop 2kW power single cells and demonstrate stacked cells of >5kW output power; in phase 2, the team will build and test a complete breadboard 5kWe system integrating a fuel cell stack and reformer and meeting stringent weight and power requirements of the REEACH program.

Potential Impact:

Electrified aviation propulsion systems have the potential to achieve ultra-high fuel-to-propulsive power conversion efficiencies compared with existing turbofan and turboprop systems.


This program could ensure U.S. technology leadership in ultra-high efficiency aircraft propulsion systems capable of exploiting CNLFs.


A high specific power electrified propulsion system framework could enable net-zero carbon aviation by facilitating the transition to carbon neutral liquid fuels (CNLFs) while meeting all mission requirements.


The developed ESPG sub-system could provide the foundational technology for a new industry in ultra-high efficiency propulsion systems while improving the competitiveness of the existing air transportation industry by reducing fuel costs.
