The invention relates to a device (1) for disintegrating particles (3) of a suspension with ultrasonic sound. The device (1) comprises a channel (10) for a suspension, wherein the channel (10) comprises a particle processing portion (12).
The invention relates to a method for producing gas diffusion electrodes (GDEs) for fuel cells, which gas diffusion electrodes comprise at least one electrically conductive carrier (4) and at least one catalytic layer (3) containing noble metal on the carrier (4). Particles containing noble metal and non-metal conductive particles are alternately applied by physical gas-phase deposition on the electrically conductive carrier (4) in order to produce the catalytic layer (3).
