Description
Ji Hee Kwon, Jinnyeong Jo, and Byeong-Seon An tune imaging of fuel cell layers in this 2026 study. The layers sit at the cathode of proton exchange membrane fuel cells, and their pores shape performance. A focused ion beam cuts cross sections for microscope viewing, but bad settings mar the cut.
The team varied beam voltage, current, and cold conditions. Milling at high voltage and low current cut the streaking flaw and matched the pore look of cold milling. That means room-temperature cuts, done right, can serve pore studies. Reliable images matter because pore counts guide cell design. The paper gives labs a tested recipe.
