(2) Customer's Systems Integration

Systems level optimization is the key to Palcan's integrated product solution strategy. Design and manufacturing knowledge relating to core component and subsystem development in key systems gives the Company a significant advantage over competitors who are simply integrating purchased components. In addition to the previously mentioned technologies, the Company's system integration technologies and knowledge include:

• Design, modeling, analysis and optimization of PEM fuel cell systems
• Fuel, air and water management systems
• Multivariable adaptive controller and power electronics

• Scooters
• Electric Bikes
• Wheel Chairs
• Golf Carts
• Marine Propulsion Units
• Auxiliary Power Units (for trucks and recreation vehicles)
• Portable Auxiliary Power Units
• Portable Battery Re-chargers
• Integrated Photovoltaic Fuel Cell Power Modules

Run time at maximum power output 5 hours Fuel supply 1,800 liters of hydrogen stored in 6 canisters. Supplied connections for external hydrogen supply on front panel. Operating temperature 5-40°C Output 110-120V AC /500W Or 220V AC /500W Dimensions Width 53cm; Depth 47cm; Height 50cm
