Micromachined electrolyte sheet, fuel cell devices utilizing such, and micromachining method for making fuel cell devices
A sintered electrolyte sheet comprising: a body of no more than 45 μm 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 μm, 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.
