Ice in fuel cells imaged directly for the first time

Researchers from the Paul Scherrer Institute (PSI) have succeeded in imaging the distribution of frozen and liquid water in a hydrogen fuel cell directly for the first time. They applied a new imaging technique that uses successively two beams with different neutron energies to distinguish between areas with liquid water and those with ice extremely reliably. The method therefore opens up the prospect of studying one of the main problems of using fuel cells to power vehicles: ice can clog the pores in the fuel cells and affect their performance.

Surface segregation acts as surface engineering for the oxygen evolution reaction on perovskite oxides in alkaline media

PSI researchers have studied the influence of surface segregation on the oxygen evolution reaction (OER) activity for the, La_0.2Sr_0.8CoO_3-_d (LSCO) perovskite, one of the most active perovskite towards the OER in alkaline electrolyte. It has been found that the higher the perovskite synthesis temperature the more strontium segregation occurs on the surface.
