Fuel Cell Systems
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.
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. Swiss Hydrogen
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.

Hy.Muve Road Sweeper
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.
Pac Car II
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.
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.
The 30 kW fuel cell powered VW Bora was created 1998. The system was realized in a collaboration of Volkswagen, PSI and ETH Zürich.
