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: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
