Abstract
This work is directed to the study and evaluation of gas diffusion electrodes as detectors inhydrogen sensors. Electrochemical experiments were carried out with rotating disk electrodes with a thin
porous coating of the catalyst as a previous step to select useful parameters for the sensor. An experimental
arrangement made in the laboratory that simulates the sensor was found appropriate to detect volumetric
hydrogen percentages above 0.25% in mixtures H 2 :N 2 . The system shows a linear response for volumetric
percentages of hydrogen between 0.25 and 2 %.
