Název v původním jazyce

Influence of hydrogen contamination by mercury on the lifetime of the PEM-type fuel cell

Popis výsledku v původním jazyce

The subject of this study is the influence of traces of mercury present in the hydrogen originating e.g.from the amalgam technology of brine electrolysis on the lifetime of PEM-type fuel cell. Accelerated tests were used in order to record deteriorationof laboratory fuel cells? performance. The power output decrease observed was only partly reversible. As was proven by XPS spectroscopy, the cell performance deterioration originates from the interaction between mercury and the platinum catalyst. The lifetime of the fuel cell was assessed on the basis of the experiments performed as 7000 h for an average mercury concentration in the hydrogen of 10gNm-3. This is a sufficient value to permit utilization of the hydrogen from this source as a fuel for the fuel cell. It should be kept in the mind, however, that this value was obtained on the basis of the accelerated durability tests.
