Neutron imaging for automotive polymer electrolyte fuel cells during rapid cold starts

Abstract

neutron imaging system to visualise the water distribution inside an automotive single cell simulating a fuel cell stack during cold starts. This was achieved using a rapid heating unit. In addition, we showcased cold-start tests at three different sub-zero temperatures, and the obtained results suggest that pre-conditioning residual water and post-cold-start meltwater have an impact on the rapid cold-start performance.
