Diesel-powered fuel cell generates green electricity

14.07.2015

The research partners Volvo Technology (Sweden), Johnson-Matthey (United Kingdom), Modelon AB (Sweden), PowerCell AB (Sweden), Jožef Stefan Institute (Slovenia), Forschungszentrum Jülich (Germany) and Fraunhofer ICT-IMM (Germany) have reached their final goal by the end of the FCGEN project: they have developed a diesel-powered fuel cell system and successfully demonstrated its functionality in autonomous operation mode.

The system consists of a diesel and a water tank, a hydrogen generating module (reformer) and a fuel cell module including a low-temperature-PEM-fuel-cell (LT-PEM) with 55 cells as well as a battery and power electronics.

The system is designed for the use in truck, recreational vehicle and yacht applications. It generates up to three kilowatts electrical power but can easily be modified for larger power ranges. Therewith enough output is available to run electric and electronic small consumers as well as „power guzzlers” like for instance air conditioning or refrigerators.

Hydrogen generation from diesel

To extract the hydrogen, which is needed for the fuel cell, out of the Diesel, the Diesel fuel in the tank is converted into a hydrogen-rich gas by autothermal reforming. This process was developed at Forschungszentrum Jülich and has already proven its high stability for a duration in the range of 10,000 hours.

Carbon monoxide which is also generated by the reforming process is initially converted to a remaining low concentration (< 10 ppm) by means of further reactors (plate heat exchangers by Fraunhofer ICT-IMM) being part of the fuel processor. This is also valid for the sulfur which is contained in the fuel in minor amounts. The resulting gas is primarily composed of hydrogen, carbon dioxide and steam of which the hydrogen is processed in the fuel cell to generate electricity.

Fuel cell system as environmentally friendly option

The catalytic processes needed to convert diesel fuel were realized by using catalysts made by the catalyst producer Johnson-Matthey. The fuel cell developed by PowerCell is characterized by a high long-term stability. The whole system is started up by the combustion of diesel fuel and is running fully automated thanks to the control system developed at the Jožef Stefan Institute. The battery of the system is recharged automatically by the fuel cell.

In the power range from three to ten kilowatt so far only gasoline or diesel fueled electricity generators based on combustion engines (APU) are available at the market. The FCGEN fuel cell system is working with a low noise emission and is virtually environmentally compatible. A further development of the system is planned.

The FCGEN project was funded by the European Community Joint Technology Initiative Hydrogen and Fuel Cells.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
