Over‐humidification is a critical challenge to the performance and durability of polymer electrolyte fuel cells (PEFCs). This review evaluates current methods for detecting quantifying over‐humidification, focusing on simulation, imaging, sensor technologies. Each method assessed based five key criteria: precision, sensitivity, real‐time capability, interpretation complexity, validation strength. Physically grounded modeling approaches such as computational fluid dynamics lattice Boltzmann offer high accuracy but are computationally demanding. Imaging techniques, including neutron imaging magnetic resonance provide valuable insight face limitations regarding scalability application. Sensor technologies, from commercial sensors artificial intelligence–enhanced nanostructured platforms, enable monitoring require improved robustness under operando conditions. By comparing these techniques individually collectively, this identifies promising hybrid strategies outlines research priorities achieving intelligent, water management in PEFCs.
