Abstract
Embodiments of the disclosure relate to membrane electrode assemblies. The membrane electrode assembly may include at least one gas-diffusion layer having a first side and a second side, and particle cores adhered to at least one of the first and second sides of the at least one gas-diffusion layer. The particle cores includes surfaces adhered to the at least one of the first and second sides of the at least one gas-diffusion layer and surfaces not in contact with the at least one gas-diffusion layer. Furthermore, a thin layer of catalytically atoms may be adhered to the surfaces of the particle cores not in contact with the at least one gas-diffusion layer.
Claims14
A membrane electrode assembly, comprising:
- at least one gas-diffusion layer having a first side and a second side;
- at least one proton exchange membrane attached to at least the first side of the at least one gas-diffusion layer;
- and
- an electrocatalyst further comprising:
- particle cores directly adhered to at least the first side of the at least one gas-diffusion layer, wherein the particle cores include a first surface area adhered to the first side of the at least one gas-diffusion layer and a second surface area not in contact with the at least one gas-diffusion layer;
- and
- a thin layer of catalytically active metal atoms adhered to the second surface area of the particle cores not in contact with the at least one gas-diffusion layer, and not adhered in-between the first surface area of the particle cores and the first side of the at least one gas-diffusion layer.
