Fuel gas sensitive electrode material for electrochemical sensors

摘要

the invention concerns a elektrodenmaterial for electrochemical sensors, in particular for brenngassensitive sensors.for such applications it is $a perowskitische elektrodenmaterialien known but by changing its sauerstoffstu00f6chiometrie considerable ladungstru00e4gerbeweglichkeit).these defects are the cause for an additional catalytic activity in oxidationsprozessen at the electrodes.the measurement of hydrocarbons from brenngasen is distorted in such elektrodenmaterialien.$a in the erfindungsgemu00e4u00dfen elektrodenmaterial the aforementioned disadvantages overcome that mischoxide with non perowskitischer crystal structure are used.the $a composition of the general formula i and (d) bxc5 - xo12u00b1 or d1 or d2 yb1 - xcxo4u00b1 yb8 - xcxo16u00b1 or d2 yb1 - xc1 - xo5u00b1 or d2 ybxc2 - xo7u00b1 showwith a or / and d a unterstu00f6chiometrisch spent cation from the number of the lanthanides or inclusions, b a multivalentes ion and c ion is a redoxstabiles.
