ELECTRODE FIBRE, ELECTRODE, ELECTROLYSIS CELL AND PROCESS FOR PRODUCING THE ELECTRODE FIBRE AND THE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2023/143771
Kind Code:
A3
Abstract:
The invention relates to an electrode fibre (3) having a stainless steel fibre (1) which comprises a stainless steel in which the fraction of Ni is at least 1% by mass, more particularly at least 8% by mass, and having an adhesive coating (2) applied directly on the stainless steel fibre (1) and enveloping the stainless steel fibre (1), in which the fraction of Ni is at least 80% by mass, and having a catalytic layer (3) applied directly on the adhesive coating (2) and enveloping the adhesive coating (2) and also comprising a first alloy which contains Ni and Fe with a cumulative fraction of Ni and Fe of at least 90% by mass in the catalytic layer (3), or comprising a second alloy which contains Ni and Co with a cumulative fraction of Ni and Co of at least 90% by mass in the catalytic layer (3), or comprising a third alloy which contains Ni, Co and Fe with a cumulative fraction of Ni, Co and Fe of at least 90% by mass in the catalytic layer (3).
