To reach a better CO conversion, it is possible to add a low-temperature shift reactor, which increases the CO2 capture rate (see also Fig. 10.3). If both clean CO2 for storage and clean hydrogen for fuel cell applications are required, a combination of a C02-capture plant (e.g., absorption with Rectisol) and a PSA plant is necessary. If only pure hydrogen is required, a PSA unit would be sufficient (and is standard practice), but the C02 stream would be contaminated by impurities, such as H2, N2 or CO, which have to be removed for geological storage.

Researchers at Lehigh University are developing a methanol reforming silicon reactor with a palladium membrane for a hydrogen purification system built using semiconductor fabrication techniques. The device is designed to produce hydrogen for fuel cells for portable electronic devices, such as laptop computers and cell phones.

The Finnish budget for MFC work is divided into fuel cell R D and hydrogen. For fuel cells, the budget from 1995 through 2002 was 11.5 million. For 2003, it was 4 million. For hydrogen, the budget from 2000-2002 was 0.68 million. For 2003, it was 1.4 million. 

Water Electrolysis. An example of the use of computers in pattern recognition can be given from work on the use of coal slurries to provide alternative anodic reactions in the electrolysis of water, with the aim of producing cheap hydrogen for fuel cells. In the presence of the coal slurries, the evolution of oxygen (the usual anodic reaction in the electrolysis of water) does not occur. Instead, a large number of... 

As CO is highly toxic, and causes respiratory problems, its elimination is quite important Industrially, CO elimination is required for C02 laser application, and the production of pure hydrogen for fuel cells. Catalysis testing of the reaction has been performed, independently, with an IR gas-sensor by Hoffmann et al. and with a combustible CO gas sensor by Yamada et al. [25, 26]. In both groups, C02 produced by CO oxidation was quantified by an IR gas-sensor. 

This chapter deals with development work in the field of micro structured fuel processors, which convert various fuels to hydrogen for fuel cells and other power generation modules. 

Large-scale production of hydrogen for fuel and chemicals starts from fossil fuels, typically by methane steam reforming (MSR) and WGS processes. 

Note that the manufacture of A1 occurs from plentifully available natural resources at present this is bauxite and eventually it will be clay. The electricity for many aluminum plants comes from hydroelectric plants, so that the use of mechanically rechargeable A1 batteries (obtained in this manner) would lead to a reduction in greenhouse gases faster than that of re-forming methanol on-board cars to obtain hydrogen for fuel cells (because this gives rise to C02).
