Fuel Cells: Oxidation processes of phosphoric acid revealed by tender X-rays

Options for increasing the lifetime and efficiency of fuel cells

05-Apr-2024 - The interactions between phosphoric acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded the multiple oxidation processes at the platinum-electrolyte interface. The results indicate that ...

Water distribution in the fuel cell made visible in 4D

The analysis opens new possibilities for more efficient and thus more cost-effective fuel cells

09-Jun-2022 - Teams from Helmholtz-Zentrum Berlin (HZB) and University College London (UCL) have visualised the water distribution in a fuel cell in three dimensions and in real time for the first time by evaluating neutron data from the Berlin Experimental Reactor shut down in 2019. The analysis opens new ...

How new materials increase the efficiency of direct ethanol fuel cells

Composite membrane consists of Nafion with embedded nanoparticles

06-May-2020 - A group from Brazil and an HZB team have investigated a novel composite membrane for ethanol fuel cells. It consists of the polymer Nafion, in which nanoparticles of a titanium compound are embedded by the rarely explored melt extrusion process. At BESSY II they were able to observe in detail, ...
