2. Introduction
2007:
Belenos Clean Power Holding was founded by N.G. Hayek to develop a sustainable energy chain starting from solar energy
Prestigious partners were associated to the project: Swatch Group Ltd, Hayek Engineering, Deutsche Bank, Swiss Federal Institute of Technology Zurich, Paul Scherrer Institut, Ammann-Group, Group E and actor George Clooney
Since 2008:
Development of a unique FC system running on Hydrogen and pure Oxygen in partnership with the Paul-Scherrer-Institute (PSI)
Since 2011:
Development of Hydrogen/Air FC system for mobile applications. Redesign of H2/O2 FC system for stationary applications
Since 2012:
Development of a PEM electrolyser for the production of hydrogen fuel from water and renewable energy

11. Belenos Fuel Cell System
Proprietary design of fuel cell stack and FC system
Development of low cost PEM membrane with excellent durability in collaboration with PSI
Bipolar plate development with leading supplier for stationary FC systems
Integrated system components for improved performance and reduced cost
Production capacity for 1MW/month available

12. Advantages H2/O2 FC over H2/Air FC
Higher system efficiency
% with H2/O2 vs % with H2/Air
Significantly lower cost
Power density (W/cm2 active area) is twice as high at same efficiency
80% of FC cost is active area cost (bipolar plates and MEA)
Better reliability
Very simple system
Very few moving parts
Fast start-up
Full power achievable within a few seconds
No startup-time and -energy for air compressor required
Independent from ambient air conditions
Operation at high altitudes possible
Operation at any ambient temperature and humidity possible
No degradation due to air pollution

13. FC system efficiency
Belenos H2/O2 FC System efficiency compared to Hydrogenics HyPM HD 16, one of the most efficient systems on the market
This performance can be reached due to a very high cell efficiency and extremely low parasitic losses
(U/I curve measured with 6 cell stack with 200 cm2 active area at 3.5 barabs and 75 °C)

14. Hybrid - fuel cell/battery - EV
The fuel cell system doubles the range of the vehicle.
The fuel cell could also drive the vehicle when the HV battery is empty (with limited power).
