The results tested by potentiodynamic and ...
Ordinary stainless steel bipolar forceps lack the heat transfer needed to prevent hot spots on the forceps tips during coagulation, which can cause residuals to stick to tips. Silver alloy allows the surgeon to complete coagulation procedures without frequently wiping of tips.
Stainless steel samples (SS304), acting as bipolar electrodes, were immersed in sulphuric and hydrochloric acid and exposed to an electric field to establish a potential gradient along the surface. In this way, the same steel sample was exposed to a wide range of cathodic and anodic conditions, ranging from potentials yielding hydrogen ...

Uncoated stainless steel and uncoated titanium as bipolar plates Austenitic SS, which contains of chromium and nickel elements, has better corrosion resistance [68] . A chemical attack in the PEMFC affects the corrosion resistance of metals because of their chemical composition and the alloying elements on the metals surface [69] .
Stainless steel has excellent electrical conductivity/thermal properties, corrosion resistance and mechanical properties, and is the first choice for bipolar plate materials. However, this kind of material has poor corrosion resistance in the battery environment, and the conductivity of the passivation film formed on the surface is low.
A novel bipolar electrode made of pure platinum and stainless steel was developed for prostate cancer ablation. Voltages of 500 and 700 V were …

Stainless steel bipolar plates for use in proton exchange membrane (PEM) fuel cells have been identified as a lighter and cheaper alternative to graphite plates. Current manufacturing of metal bipolar plates by hydroforming or micro-stamping leads to excessive stretching of the material and therefore limits the channel depths that can be formed.
