Large-area imager of hydrogen leaks in fuel cells using laser-induced breakdown spectroscopy

M. Hori, R. S. Hayano, M. Fukuta et al. We constructed a simple device, which utilized laser-induced breakdown spectroscopy to image H gas leaking from the surfaces of hydrogen fuel cells to ambient air. Nanosecond laser pulses of wavelength lambda=532 nm emitted from a neodymium-doped yttrium aluminum garnet laser were first compressed ... [Rev. Sci.
