Hydrogen from Proton Exchange Membrane Water Electrolysis (PEMWE) cells enables the storage of sustainably generated energy. The efficiency and longevity of these cells depend on operating conditions such as the temperature of the membrane. We set up a fiber sensor using lanthanide-doped nanoparticles as nanothermometers and employed it to measure the temperature at the cell's membrane for different operational conditions. The results will help us to optimize the cell's operational parameters. The sensor is also applicable in strong electromagnetic fields, for example in battery technology or magnetic resonance tomography.
