Cations found to be culprit behind degraded platinum electrodes

Electrochemical devices like batteries and fuel cells help power our modern lives. These devices traditionally contain a liquid electrolyte sandwiched between solid electrodes, and can generate electricity through chemical reactions, or alternatively, can undergo chemical reactions when subjected to an electrical current. Electrochemical devices like batteries and fuel cells help power our modern lives.
