Abstract
Electrodes and electrocatalyst layers incorporating modified carbon products. The modified carbon products may advantageously enhance the properties of an electrode or electrode layer, leading to more efficiency within the a fuel cell or similar device.
Claims62
An electrocatalyst, said electrocatalyst comprising an active species phase dispersed on a carbon support structure, wherein said carbon support structure is a modified carbon product.
A method for making an electrocatalyst, comprising the steps of:
- a) providing a carbon support;
- b) covalently attaching a functional group to said carbon support to form a modified carbon support product;
- and
- c) depositing an active species phase on said modified carbon support product to form an electrocatalyst.
A method for making an electrocatalyst, comprising the steps of:
- a) providing an electrocatalyst particle comprising an active species phase dispersed on a carbon support phase;
- and
- b) modifying said carbon support by covalently attaching a functional group to said carbon support to form a modified carbon support phase.
