Abstract
This disclosure is about invention of fuel cells comprising vertically free-standing graphene-containing carbon nanosheets in the components, and methods of making thereof. Performance enhancement effect of the fuel cell is achieved by using vertically free-standing graphene-containing carbon nanosheets as: 1) surface coating of electrically conducting components, 2) and/or a geometric geometric structural supporter of additive catalyst materials, 3) and/or a synergic catalytic nano-composite
Claims5
A fuel cell, comprising:
- a cathode;
- an anode;
- and
- an electrolyte,
- wherein a plurality of vertically free-standing graphene-containing carbon nanosheets, of which the thickness is 2 nanometers or less, having a base layer of planar one to seven atomic layers graphene materials, having folded and crumpled topological structure, grow up on surfaces of the cathode and/or the anode, by a plasma technology.
A gas diffusion layer (GDL) as a component of a fuel cell, which has a plurality of vertically free-standing graphene-containing carbon nanosheets, of which the thickness is 2 nanometers or less, having a base layer of planar one to seven atomic layers graphene materials, having folded and crumpled topological structure, growing up on the GDL surface.
A membrane electrode assembly (MEA) as a component of a fuel cell, wherein a plurality of vertically free-standing graphene-containing carbon nanosheets, of which the thickness is 2 nanometers or less, having a base layer of planar one to seven atomic layers graphene materials, having folded and crumpled topological structure, grow up between a gas diffusion layer (GDL) surface and an electrolyte layer.
