Journey to the heart of a fuel cell in operation

CNRS Chimie highlights a ground-breaking experiment carried out under operando conditions using an environmental transmission electron microscope. This study, published in the journal Nature Communications, enables the evolution of the microstructure of fuel cell components to be observed on a nanometric scale during operation. This work provides crucial observations for optimising the lifespan and efficiency of these energy conversion devices.
