1. A method for monitoring degradation of a fuel cell membrane in a proton exchange membrane fuel cell, the method comprising:
disposing a first microsensor inline with a first exhaust of the proton exchange membrane the cell, the first microsensor configured for sensing a first analyte that is fluorine, the first microsensor being an ion-sensitive field effect transistor, and the ion-sensitive field effect transistor comprising a fluoride-sensitive membrane as a thin laver of insulator in the first microsensor;
detecting, by the first microsensor, fluorine ions in the first exhaust of the proton exchange membrane fuel cell, based on interaction of the fluorine ions with the fluoride-sensitive membrane of the first microsensor, to give first sensing data comprising a level of the first analyte present in the first exhaust of the proton exchange membrane fuel cell:
transmitting, by the first microsensor, the first sensing data to a processor in operable communication with the first microsensor; and
performing, by the processor, a deep learning algorithm on the first sensing data to enable predictive maintenance on the fuel cell membrane of the proton exchange membrane fuel cell,
the fluoride-sensitive membrane comprising at least one of LaF3 and CaF2.
