Development of fuel cell system technologies for achieving competitive solutions for aeronautical applications

Driven by the demand for optimised aircraft performances, reduced operating and maintenance costs, increased dispatch reliability, reduced greenhouse gas emissions and quieter aircrafts, and the rapid growth of air traffic for the coming years, both commercial aircraft industry and general aviation are respectively pushing towards the concept of more electric aircraft (MEA) for which electricity is initially used for non-propulsive systems, and for an all-electric aircraft. As highly efficient power generation systems, fuel cell systems can play an important role in the development of the MEA concept.

Target applications range from cabin/hotel loads (5-20 kW), to emergency power units (15-50 kW), Auxiliary Power Units (superior to 50 kW) or regarding general aviation to the light aircraft propulsion systems (> 40 kW). Besides commercial aircraft industry and general aviation, electrical unmanned aerial vehicles (UAV) have also shown interest for fuel cell technology as a key means to offer an improved endurance and range mission capability. Previous (Boeing 2008, DLR A320 ATRA 2011, Antares DLR 2009 and 2012, FCH-JU SUAV 2011) and current (FCH JU funded HYCARUS) projects have demonstrated and confirmed the potential of fuel cell technology to match aircraft needs and have helped identify main remaining challenges and bottlenecks.

Main challenges for fuel cell based energy generation systems for the aircraft industry include the fuel cell system weight and volume, the required extended lifetime and reliability to comply with aircraft operation and maintenance schedules, the ability of the technology to demonstrate compliance with the specific aerospace airworthiness certification requirements (essentially related to safety considerations) , the cost effectiveness of the corresponding fuel cell system designs and their full integration into the aircraft.

Cele

The objective of the project is the design, development and demonstration under realistic operating conditions (TRL5-6) of an autonomous electric power generation system for non-intrusive applications for auxiliary or emergency power generation.

The consortium should be established to gather required competences and background knowledge to address the above mentioned challenges and the following key objectives:

  • Fuel cell system electric power output of at least 10 kW, according to target application power range;
  • Pure hydrogen fed fuel cell system;
  • Develop corresponding key components and subsystems to achieve compliance with aerospace requirements (weight and power density, safety, lifetime, materials selection, DO160, EASA CS-VLA, EASA CS23 etc) with a particular focus on key equipment such as fuel cell, air compressor and H2 storage and distribution subsystem. Later, industrialisation and target aircraft installation should be strong key drivers for any of the considered prototype developments and this should be well documented in the proposal;
  • Implement simulation and model-based design methodology for optimal design trade-offs (performance, durability) and definition of most suitable control strategies;
  • Demonstration of FC system compliance with applicable aerospace Regulations Codes and Standards (RCS) for the considered application and identification of amendments/evolutions of existing RCS when required;
  • Demonstration of system operation and performance under realistic operating conditions representative of the selected application mission profile (validation of operating strategies and assessment of their impact at system level);
  • Experimental demonstration at laboratory level of system prototype durability and assessment of system reliability and maintainability under real operation;
  • Perform economic assessment and derive fuel cell system Total Cost of Ownership for the selected target application including refueling and system maintenance.

Throughout the project, particular attention should be given to meet the best achievable trade-off between performance, lifetime, reliability, maintainability and system power density. Safety is hereby to be maintained at the required level. Project activities may enable even higher safety levels.

Proposals are also encouraged to consider preparation of flight test demonstrations to be conducted after completion of the project, in order to reinforce demonstration value and representativeness and better prepare for future commercialisation of the technology within the 2025 time frame.

The consortium should include at least one aircraft OEM or one Tier 1 aircraft industry OEM.

The TRL at the start of the project should be 3-4 and the project should aim to reach a TRL of 5-6 at completion.
