Fuel Cells generate electricity through an electrochemical reaction which combines oxygen with fuel (e.g. hydrogen) to form water. The cathode of Fuel Cell captures the oxygen molecule from the atmosphere, while the anode split the hydrogen molecules into ionic state and release electrons. The hydrogen ions then swim through the membrane to react with the oxygen ions, hence forming the water.
Why Use Fuel Cells?
Higher Energy Efficiency
The reaction simplicity promises Fuel Cell with higher energy efficiency than any other conventional power source. The inherent high efficiency ranging from 35% to 55% outperforms the internal-combustion-engine generatorsí20%~30% energy efficiency. The lower heat it produces also makes the thermal highly reusable. The thermal recycle then enhances the Fuel Cellís overall efficiency to up to 90%. And +80% efficiency has been proven by Japanís 3-year demonstration project through 2005 to 2008 with more than 3300 Fuel Cell units running in households.
Clean and Eco-Friendly
The essential chemical reaction process of Fuel Cell produces water as the only byproduct. It is a carbon neutral energy solution, which can significantly cut down the carbon footprint. With no CO2 and other greenhouse gas emission, users can enjoy the clean energy without worrying about the impact the power causes.
Installation Simplicity and Operating Stability
Fuel Cells produce no vibration and noise during operation. And help users avoid the heavy smoke accompanies diesel generators. Compared with solar, wind, and other alternative energies, Fuel Cell systems require less space and can operate stably 24 hours/ 365days regardless the weather and geographic constraint.
Which permit Fuel Cells of high installation flexibility, both indoor and outdoor, and insure the user constant power supply.
With more than 40,000 operating hours for residential application and over 1,000 start-stop cycles for back-up power, Fuel Cell easily demonstrates its advantage for longer product life. Compared with the unpredictability and 3 to 2-year replacement cycles of lead acid batteries, Fuel Cells definitely reduce the long-term capital expenditure and the troublesome maintenance cost whilst proving the more secured power solution.
