PEM fuel cell X-ray CT study details effects of temperature and moisture on performance

Green Car Congress

If the internal conditions are too dry or too wet, the fuel cell won’t function well. Specifically, the researchers used synchrotron-based micro X‐ray computed tomography (CT) to visualize and to quantify the water distribution within gas diffusion layers subject to a thermal gradient. —Shum et al.
