Integrating FeCoNi (Iron-Cobalt-Nickel) onto conductive substrates (eg: nickel felt, titanium felt, nickel foam) creates a high-performance anode specifically engineered for the rigorous conditions of industrial alkaline electrolyzers. 

Each element in the FeCoNi system serves a specific role in improving the Oxygen Evolution Reaction (OER), which is the sluggish half-reaction in water splitting: (1) Nickel (Ni): Provides excellent chemical stability in high-molarity KOH and acts as a conductive framework. (2) Cobalt (Co): Lowers the overpotential and enhances the electronic conductivity of the surface oxyhydroxides. (3) Iron (Fe): Widely recognized as a "booster" for Ni-based catalysts. Fe atoms often act as the highly active sites in Ni(Fe)OOH structures formed during electrolysis.

Metal felt (eg: Ti, Ni, SS) is a non-woven, sintered fiber network. Its physical structure provides distinct advantages over foam or mesh for high-current applications. (1) Micro-Fiber Connectivity: The felt consists of micro-scale fibers (typically 20–80 um in diameter) that are sintered together. This creates a much more robust electrical network compared to the thinner struts of metal foam. (2) Effective Surface Area: The dense, entangled fibers provide a massive surface area-to-volume ratio, allowing for high catalyst loading without clogging the 3D transport pathways. (3) Capillary Bubble Transport: The micro-pores in the felt act as capillary channels, pulling electrolyte in and pushing oxygen bubbles out more efficiently than larger-pore foams. This minimizes "gas shielding," which is the primary cause of efficiency loss at high current densities.
