Step by step: becoming a leading company for fuel cell technology



Researchers and developers at Sulzer AG initiate the "HEXIS" project (Heat Exchanger Integrated Stack).



Based on the "HEXIS" business concept, Sulzer Hexis AG is founded as a venture division of the corporation. In the following years, development engineers and materials scientists make significant progress in the areas of materials development, process control and system integration.



Hexis AG, still a venture division of the Sulzer Corporation, receives the f-cell Gold Award for the development of the "Galileo 1000 N" fuel cell heater. This innovation award honours outstanding, application-oriented developments in the field of fuel cells. In this same year, the "Galileo 1000 N" is CE-certified.



In January, the company becomes independent and operates under the name HEXIS AG. As an investor, the Foundation for Art, Culture and History in Winterthur ensures the long-term continuation of research and development.

In the same year, HEXIS initiates the fuel cell network "Swiss SOFC Consortium", in which scientists from various Swiss universities and companies work to further develop the SOFC. HEXIS is now one of the world's leading companies for fuel cell technology. 



The fuel cell heater "Galileo 1000 N", developed by the HEXIS team, has been tested under real conditions since the beginning of 2007 in cooperation with partners from the energy supply industry. 

Oriented towards the most important European market for micro co-generation, the subsidiary HEXIS GmbH is founded in the spring of 2007 in Konstanz, Germany.



HEXIS is invited by the German fuel cell industry to take part in the practical home-use fuel cell test called Callux. This project, supported by the German Federal Ministry of Transport, Building and Urban Affairs and NOW GmbH (the National Organisation for Hydrogen and Fuel Cell Technology), as part of the National Innovation Programme for Hydrogen and Fuel Cell Technology (NIP), aims to prepare for the market launch of natural-gas-powered fuel cell heaters.

Callux starts in autumn 2008. In December, HEXIS establishes a sales and servicing partnership with the two heating technology manufacturers Hoval Corporation, in Vaduz (Liechtenstein) and Stiebel Eltron GmbH & Co. KG, in Holzminden (Germany).



HEXIS passes the first assessment in Callux. Equipment specifications and field testing meet expectations.



HEXIS and Empa in Dübendorf (Switzerland) agree on a strategic partnership in research and development. Empa is an interdisciplinary research and service institution for materials science and technology development within the ETH sector, which includes federal universities and application-oriented research institutes.



Major advances in the reliability and longevity of the Galileo fuel cell system have been confirmed by extensive testing and practical usage. The second Callux assessment has also been passed. In the spring of 2011, Vau3, the third generation of "Galileo 1000 N", is presented.

HEXIS announces its market entry, targeted to end customers, in mid-2013. The company expresses this marketing strategy by revising its corporate identity, which leads to a new corporate design in autumn.



Since September 2012, in addition to the Foundation for Art, Culture and History (in Winterthur, Switzerland), the Viessmann Group (in Allendorf, Germany) has joined as another HEXIS partner whose market and technology expertise is helping to advance the fuel cell business. The European demonstration project Ene.field is launched, in which HEXIS and other manufacturers from the heating industry together with partners from the energy industry strive to introduce fuel cell heating devices to the market.



HEXIS supplies the last 30 of a total of approximately 220 fuel cell heaters to German energy supply companies as part of the Callux project. At the end of this year, HEXIS is one of the first companies in Europe on the market with the launch of the fuel cell heater Galileo 1000 N.



After Viessmann had already acquired 50 percent of HEXIS from the Foundation for Art, Culture and History in 2012, the remaining half is also acquired by Viessmann. Thus, the Viessmann Group makes a clear commitment to highly efficient and low-CO2 fuel cell technology.


The Callux practical test will finish at the end of June. The positive experiences from Callux motivated us to venture into the market at the end of 2013. About 80 Galileo 1000 N devices were successfully installed as part of the European field test project Ene.field. As the fuel call supplier for Viessmann, HEXIS is also a project partner in the EU project "PACE". This project is funded by the European Commission as a part of "Horizon 2020". The focus here is on the market launch of fuel cell heating devices in Europe, with the targeted installation and operation of 2,650 devices from all participating manufacturers.



The market launch of Galileo 1000 N in 2013 significantly increased awareness of fuel cell technology. Over 120 devices have been sold in Switzerland, Germany, Austria and other countries. All available fuel cell heaters were marketed successfully. We are ensuring that our customers have sufficient stocks of spare parts into the future. The first zero series of the Galileo successor is delivered and tested by Viessmann in the German town of Allendorf and by HEXIS in Winterthur. Our customers can purchase the successor to Galileo from Viessmann.

The first zero series of the Galileo successor is produced and tested by Viessmann in the German town of Allendorf and by HEXIS in Winterthur. At the end of October, HEXIS looks back on the successfully completed EU fuel cell demonstration project "Ene.field", which provided valuable experience in understanding user expectations and quality improvement.
