Abstract
One embodiment includes a method of forming a hydrophilic particle containing electrode including providing a catalyst; providing hydrophilic particles suspended in a liquid to form a liquid suspension; contacting said catalyst with said liquid suspension; and, drying said liquid suspension contacting said catalyst to leave said hydrophilic particles attached to said catalyst.
Claims22
A method comprising:
- providing a catalyst;
- providing hydrophilic particles suspended in a liquid to form a liquid suspension;
- contacting said catalyst with said liquid suspension;
- and,
- thereafter drying said liquid suspension contacting said catalyst to leave said hydrophilic particles attached to said catalyst wherein said hydrophilic particles comprise hydroxyls bonded to a surface of each of said hydrophilic particles with the proviso that the hydrophilic particles do not include ruthenium.

A method comprising:
- providing a thin film catalyst;
- providing hydrophilic particles suspended in a liquid to form a liquid suspension;
- contacting said catalyst with said liquid suspension;
- and,
- thereafter drying said liquid suspension contacting said catalyst to leave said hydrophilic particles attached to said catalyst wherein the hydrophilic particles are coated onto the catalyst by contacting a rod covered with the suspension to the catalyst surface and wherein said hydrophilic particles have surface areas of about 20 M2/g to about 250 M2/g and wherein said hydrophilic particles comprise hydroxyls bonded to a surface of each of said hydrophilic particles with the proviso that the hydrophilic particles do not include ruthenium.
2 more elements
A method comprising:
- providing a thin film catalyst;
- providing hydrophilic particles suspended in a liquid to form a liquid suspension;
- contacting said catalyst with said liquid suspension;
- and,
- thereafter drying said liquid suspension contacting said catalyst to leave said hydrophilic particles attached to said catalyst wherein the hydrophilic particles are coated onto the thin film catalyst by forcing the liquid suspension through a slot positioned above and moved over the thin film catalyst surface and wherein said hydroplilic particles are formed by flame pyrolysis wherein said hydrophilic particles comprise hydroxyls bonded to a surface of each of said hydrophilic particles with the proviso that the hydrophilic particles do not include ruthenium.
2 more elements
A method comprising:
- providing a catalyst;
- providing hydrophilic particles suspended in a liquid to form a liquid suspension;
- contacting said catalyst with said liquid suspension;
- and,
- thereafter drying said liquid suspension contacting said catalyst to leave said hydrophilic particles attached to said catalyst wherein said hydrophilic particles comprise hydroxyls bonded to a surface of each of said hydrophilic particles and wherein said hydrophilic particles consist of silicon dioxide.
