PROBLEM TO BE SOLVED: To provide a method of machining sintered electrolyte sheets and fuel cell devices which is used to: cut the electrolyte sheets and/or fuel cell device components to appropriate sizes; trim the edges of the sintered electrolyte sheets or fuel cell devices; and/or form via holes and surface modifications or patterns.SOLUTION: A sintered electrolyte sheet comprises: a body with a thickness of 45 μm or less; and at least one laser machined feature 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, where said laser has a wavelength less than 2 μm, a fluence less than 200 J/cm, a repetition rate (RR) between 30 Hz and 1 MHz, and a pulse duration less than 1 μs. |
