Ammonia removal from the reformate<\/h2>\n
\n
\n

Increasing the lifetime of fuel cell systems<\/p>\n

\n

Due the lack of hydrogen infrastructure, which is necessary for the operation of PEM fuel cell, it must be in power supply applications in medium term generated locally on site. One promising possibility is the use of hydrocarbons as an energy source, such as the already existing in large scale natural gas infrastructure.<\/p>\n

That by reforming produced hydrogen-rich gas mixture may also contain contaminating and trace gases that affect the performance of the fuel cell or even lead to permanent damage of the fuel.<\/p>\n

As part of the research project IGF-16199N the formation of the PEM fuel cell\u00a0poisoning component ammonia<\/b>\u00a0(NH3<\/sub>) by\u00a0steam reforming<\/b>\u00a0of nitrogen-containing natural gases was systematically investigated.<\/p>\n

Dependencies with respect to the nitrogen content of the gas, the catalysts used and the space velocity were determined. In addition, the catalysts of reformer, CO-shift and CO-purification were subjected to ammonia tolerance tests.<\/p>\n

Investigations for\u00a0ammonia removal by solution in water<\/b>\u00a0for various process variants were tested and evaluated on your NH3<\/sub>-cleaning ability.<\/p>\n

Finally based on the findings an optimized modular\u00a0NH3<\/sub>-purification stage<\/b>was developed and evaluated.<\/p>\n
