Acoustic process monitoring during the structuring of diffusion media for fuel cells with Ultrashort Laser Pulses
Authors: Contents:- Diffusion media in fuel cells can be optimized through laser structuring to improve their performance characteristics.
- An optical microphone was used to monitor the process during laser structuring.
- This paper demonstrated that acoustic data can be used to monitor the laser focus position as well as material transitions in the diffusion media during structuring.
