Abstract
A method of preparing an electrode having targeted oxygen transport comprises applying a catalyst layer having active catalyst particles on a substrate, scanning the applied catalyst layer to detect the active catalyst particles in the catalyst layer, mapping the detected active catalyst particles, and forming a gas diffusion layer configured to concentrate gas distribution to the detected active catalyst particles based on the map.

A method of preparing an electrode having targeted oxygen transport, the method comprising:
- applying a catalyst layer having active catalyst particles on an electrode membrane;
- scanning the applied catalyst layer to detect the active catalyst particles;
- mapping the detected active catalyst particles;
- forming a carbon layer having a gas distribution pattern configured to concentrate gas flow to the detected active catalyst particles based on the map;
- layering the carbon layer on the catalyst layer opposite the electrode membrane;
- and
- providing a gas diffusion plate on the carbon layer, the gas diffusion plate having gas flow channels configured to deliver gas from an oxidant supply to the catalyst layer.
