Abstract
Gas-diffusion electrodes containing modified carbon products are described wherein the modified carbon product is a carbon product having attached at least one organic group. The modified carbon product can be used for at least one component of the electrodes such as the active layer and/or the blocking layer. Methods to extend the service life of electrodes as well as methods to reduce the amount of fluorine containing compounds are also described.
Claims31
A gas diffusion electrode comprising a blocking layer and an active layer, wherein said blocking layer or said active layer, or both comprise at least one modified carbon product and at least one binder, said modified carbon product comprising at least one carbon product having attached at least one organic group.
A method to improve the service life a gas diffusion electrode comprising:
- forming a blocking layer or active layer or both from at least one modified carbon product and at least one binder, wherein said modified carbon product comprises at least one carbon product having attached at least one organic group.
A method to reduce the amount of fluorine-containing compounds in a gas diffusion electrode comprising:
- forming a blocking layer, active layer, or both with at least one modified carbon product and at least one binder, wherein said modified carbon product comprises at least one carbon product having attached at least one organic group.
A gas diffusion electrode comprising at least one blocking layer or at least one active layer, wherein said blocking layer or said active layer comprise at least one modified carbon product and at least one binder, said modified carbon product comprising at least one carbon product having attached at least one organic group.
