MICROMACHINED ELECTROLYTE SHEET, FUEL CELL DEVICES UTILIZING SUCH, AND MICROMACHINING METHOD FOR MAKING FUEL CELL DEVICES

摘要

a body of no more than 45 mum thick and laser machined features with at least one edge surface having at least 10% ablation. A method of micromachining the electrolyte sheet includes the steps of: (i) supporting a sintered electrolyte sheet; (ii) micromachining said sheet with a laser, wherein said laser has a wavelength of less than 2 mum, fluence of less than 200 Joules/cm2, repetition rate (RR) of between 30 Hz and 1 MHz, and cutting speed of preferably over 30 mm/sec.
