Fuel Cell Systems

FCSystems.jpg In collaboration with industrial partners the group is providing technology support for fuel cell stacks and systems and developing proof-of-technology demonstrators. Focus today is on stationary hydrogen/(pure) oxygen systems and evaporative cooling. Current and past projects are briefly described below.

Project ESI

ESI.png The Energy-System-Integration-Platform ESI ESI Platform investigates storage of (excess) renewable energy into chemical energy such as hydrogen and synthetic natural gas. Different energy conversion systems are integrated on a platform located at the PSI East area. The fuel cell systems and diagnostics group (FCSD) being responsible for the hydrogen path consisting of an electrolyzer, a gas purification plant, hydrogen and oxygen gas tanks and a fuel cell system for reconversion to electric power, jointly developed with Swiss Hydrogen.

Autostack CORE

Autostack.jpg Autostack-CORE is a European JTI-FCH joint project developing PE fuel cell stack technology for the automotive industry. The objectives of this project are to meet the target costs while maintaining high energy density and performance. A consortium of 14 partners from industry and research was involved, with PSI being responsible for characterization performance and durability tests of short-stacks.

Belenos Fuel Cell Car

BelenosFCCar.jpg In collaboration with Belenos Clean Power Holding Belenos Clean Power AG, two generations of drive trains for lightweight cars were developed. This activity has received the Watt d'Or award in Watt d'Or award in 2011.

Post Bus

PostAuto.jpg In the frame of the FCH-JU project CHIC, Postauto Post Bus five fuel cell driven Citaro buses in daily use in the regular public transportation system in the canton of Aargau. PSI supports this project by analysis of the energy chain. The project was awarded Watt d'Or in 2012.

Hy.Muve Road Sweeper

citycat.jpg hy.muve stands for "hydrogen-driven municipal vehicle". It is a joint project between EMPA, PSI, CCEM, Bucher Schörling, BRUSA, Messer and others. A prototype of a compact road sweeper CityCat propelled with a fuel cell system is developed tested. The vehicle is currently evaluated in different Swiss cities under real live conditions. More information can be found here.

Hy.Light Car


In collaboration with Michelin a oxygen/hydrogen fuel cell system for the fuel cell based power train of the HY.LIGHT car was developed and built.


Pac Car II

paccar.jpg This is a ETHZ project developing a vehicle PAC-Car II. The fuel cell stack was provided by PSI. Using hydrogen as the fuel, PAC-Car II covers a distance of 5385 km with the energy contained in 1l of gasoline.This is the current record of minimum consumption at the shell eco-marathon.


Power Pac.jpg A new stack generation for mobile systems in the kW-range with innovative features such as internal gas humidification has been developed and characterized in collaboration with ETHZ and industrial partners. The applicability was demonstrated in the portable system PowerPac.

VW Bora
