Fuel cell catalyst layers, and related systems and methods are disclosed.

Fuel cell catalyst layer

Acidic groups such as those in the sulfonic acid family have been successfully linked onto the surface of carbon used as catalyst support. Electrodes made using such sulfonated catalysts as used in electrochemical cells improve the performance of the cells, more so than cells fabricated from electrodes using an unsulfonated electrode.

Fuel cell catalyst electrodes

In one aspect, the invention features a method including sorbing carbon monoxide to a catalyst layer of a fuel cell, and oxidizing the carbon monoxide. The method can be used to pre-condition or activate the catalyst layer.
