Performance Improvement of Proton Exchange Membrane Fuel Cells with a TiO<sub>2</sub> Sputtered Gas Diffusion Layer Under Low-Humidity Conditions

Performance Improvement of Proton Exchange Membrane Fuel Cells with a TiO<sub>2</sub> Sputtered Gas Diffusion Layer Under Low-Humidity Conditions

Proton exchange membrane fuel cells (PEMFCs) are pivotal to advancing sustainable hydrogen energy systems. However, their performance decreases under low-humidity conditions (relative humidity, RH 50%) due to inadequate membrane hydration. This study addresses this challenge by utilizing a sputterin...
