In early 2003, as part of a project partially financed by the European Union, PVFC-Sys (photovoltaic fuel cell system, Proj.nr. ERK5 - CT1999 - 00017) STMicroelectronics selected Air Liquide, to supply an Axane innovative and environmentally-friendly energy production system.

The PVFC-Sys project consists of combining a photovoltaic field with an electrolyser and a fuel cell. The photovoltaic cell produces electrical energy which, in turn is converted to hydrogen by electrolysis. The hydrogen is easily stored and then used to power the fuel cell. This combination provides high-quality, clean and silent energy since the fuel cell only produces water. Upstream of the chain, the hydrogen used to power the cell is also clean since it is obtained by electrolysis. Currently this highly reliable, « green »,  « Zero emission »  technology, the only technology of its kind, represents a possible solution for the future to meet the expectations for an alternative energy source and to produce high quality energy.

Air Liquide's involvement in the PVFC-Sys project highlights its expertise in hydrogen technologies coupled with the know-how of its subsidiary Axane in fuel cells as well as its commitment regarding sustainable development.

Air Liquide Electronics and Axane closely cooperated with the semiconductor manufacturer to build and operate this new installation on its site in Italy. The Roller Pac ™  fuel cell, with a power of 2 kW, has been operational since December 2003. Since the fuel cell was put into service, it has successfully operated continuously for nearly 1,800 hours. The fuel cell was used to provide the electricity for a room dedicated to this project by STMicroelectronics at Agrate - Italy.

This field experience clearly demonstrated the ability of the fuel cell to satisfy the energy requirements for an operational company beyond the various experiments on this subject that have been performed in laboratory conditions to date.

Commenting on this new development, Christophe Fontaine, Vice President of the Air Liquide Electronics Division declared: « This operation strengthens our already well-established links with our customer STMicroelectronics and demonstrates the benefits of hydrogen in all high-quality, clean energy production systems. Encouraged by the success of this first step, we are already working with our customers to duplicate this installation on other industrial sites. »

Renato Di Stefano, Agrate Site General Services Director at STMicroelectronics added: « ST´ s involvement in this pilot project based on renewable energy is just one example of the Company´ s long-standing commitment to environmental protection. With Air Liquide's support we have demonstrated the feasibility of the PVFC system at our Agrate site, showing that systems powered by renewable energy sources are efficient and reliable. »
