News & Highlights Energy and Environment (ENE) 28.09.2022 •Energy and Climate Damage-Repair Cycle in Hydrocarbon Based Membranes for Fuel Cells The development of next generation fuel cell membranes based on aromatic hydrocarbon chemistry calls for a new antioxidant strategy to tackle radical induced membrane degradation. Although damage by radicals cannot be prevented, the formed aromatic intermediates can be repaired by a suitable additive. Fuel cell experiments demonstrate that the approach is viable on the device level and that repair is a catalytic mechanism.

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.
