Professor Taeho Lim's research lab specializes in the development of advanced nanomaterials for clean energy applications, with a primary focus on fuel cell technologies. The lab investigates ultra-low platinum catalysts and carbon-encapsulated nanostructures to enhance catalytic stability and reduce costs in proton exchange membrane and direct methanol fuel cells. Their work addresses critical challenges such as methanol crossover and catalyst poisoning by designing functional materials that simultaneously promote oxygen reduction while suppressing methanol oxidation. Additionally, the lab explores astrophysical phenomena, including far-ultraviolet emissions in interstellar clouds, linking materials science with astronomical observations.

Ultra-stable Pt cathode catalysts in ultra-low Pt loading proton exchange membrane fuel cells were synthesized by facile carbon encapsulation.
Methanol crossover is one of the largest problems in direct methanol fuel cells (DMFCs). Methanol passing from the anode to the cathode through the membrane is oxidized at the cathode, degrading the DMFC performance, and the intermediates of the methanol oxidation reaction (MOR) cause cathode catalyst poisoning. Therefore, it is essential to develop a cathode catalyst capable of inhibiting MOR while promoting the oxygen reduction reaction (ORR), which is a typical cathode reaction in DMFCs. In t
We have constructed a far-ultraviolet (FUV) continuum map of the Taurus-Auriga-Perseus complex, one of the largest local associations of dark clouds, by merging the two data sets of GALEX and FIMS, which made observations at similar wavelengths. The FUV intensity varies significantly across the whole region, but the diffuse FUV continuum is dominated by dust scattering of stellar photons. A diffuse FUV background of $\sim$1000 CU is observed, part of which may be attributable to the scattered ph
