The OER activity and stability decreased decreasing the electrolyte pH values. By combining electrochemical studies and operando X-ray absorption spectroscopy measurements, it has been suggested that different reaction mechanisms dominate in alkaline and near-neutral electrolyte pH region. 29.05.2017 •Large research facilities •9 min To the limits of the feasible The company Daetwyler made the undulators for the X-ray free-electron laser SwissFEL of the Paul Scherrer Institute PSI, to a precision of one-tenth of the width of a hair. 16.06.2014 •Energy and Climate •7 min 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.

It has been found that the higher the perovskite synthesis temperature the more strontium segregation occurs on the surface.
