Intelligent Heat.
Clean Electricity.

HEXIS fuel cell systems combine cutting edge technology
with environmentally-friendly efficiency (A++). 

The Galileo data at a glance 



The Galileo fuel cell system, developed by HEXIS, replaces conventional gas boilers used in houses or small apartment buildings. The compact, low-emission, virtually silent system converts natural gas directly into power and heat to meet the resident's requirements. HEXIS fuel cell systems are tested according to the applicable standards and regulations and also have a CE certificate for placing the product on the market and series production.
