Cover Feature: Compound‐Specific Imaging of Methanol Fuel Cell for Performance and Degradation Studies Using a Mini Positron Emission Tomograph (Chemistry ‐ Methods 7/2021)

The Cover Feature shows a simple commercial direct methanol fuel cell in small detector ring Positron Emission Tomography (PET) camera for imaging of the electrocatalytic processes. PET images present coverage degree and distribution 11C-labeled with its derivatives along perforated plate holes anode (front) cathode (back) sides. inhomogeneous radioactivity confirms performance degradation on certain surface area catalysts. presence extent catalyst layer demonstrates undesired crossover effect.
