Current electrochemical theory does not adequately describe realistic platinum electrodes. Scientists at Leiden University have now, for the first time, mapped the influence of imperfect platinum ...
Proposed mechanism of Pt dissolution reaction considering the effect of the electrolyte components. In the case of the left figure (Li ions), the diffusion of Pt ions to the offshore (right side in ...

A new iron-based catalyst just produced green hydrogen without any platinum — slashing the cost of the reaction every fuel-cell stack depends on
A research team at Washington University in St. Louis has run a platinum-free hydrogen electrode for more than 1,000 hours at current densities that meet industrial benchmarks, a result that could ...
Most metals are negatively polarised, which protects against corrosion. However, platinum electrodes degrade quickly under these conditions. Electrolyzers and other electrochemical devices frequently ...
Degradation of platinum, used as a key electrode material in the hydrogen economy, severely shortens the lifetime of electrochemical energy conversion devices, such as fuel cells. For the first time, ...
A top-view visualization of a platinum surface during cathode corrosion. Platinum and hydrogen atoms are represented in black and white, respectively. Blue and purple triangles indicate where hydrogen ...
Scientists at Stanford Synchrotron Radiation Lightsource (SSRL) have discovered how platinum electrodes dissolve, which could lead to advancements in renewable energy. The study was published in ...
