The phrase "activation polarization" is correct and usable in written English.
It can be used in contexts related to electrochemistry, fuel cells, or battery technology to describe the voltage loss due to the reaction kinetics at the electrode surface.
Example: "The performance of the fuel cell was significantly affected by activation polarization, leading to reduced efficiency."
Alternatives: "kinetic polarization" or "reaction polarization".
After being recruited to the tumor microenvironment, TAMs differentiate into two polarized phenotypes, that is, the classic activation polarization (M1 phenotype) and the alternative activation polarization (M2 phenotype).
Correlation of Nafion loading with the activation polarization characteristics shows an initial increase of activity upto a loading of 1.3 mg/cm2 followed by a more gradual change with maxima at 1.9 mg/cm2 for both oxygen and air.
The new Ag composite electrode had minimal activation polarization by 750 °C.
The open circuit voltage, activation polarization, ohmic polarization and contact resistance are simulated simultaneously.
Degrees of activation polarization and concentration polarization related to cathodic reaction were quantified.
The effects of various physical parameters contributing to concentration, ohmic, and activation polarization are considered.
However, they suffer from a drop in the energy efficiency induced by the large activation polarization during vanadium redox reactions.
The model includes the phenomena like activation polarization, ohmic polarization, and mass transport effect present in a PEM fuel cell.
A three-dimensional model that accounts for activation polarization, ohmic polarization and concentration polarization is developed to achieve this.
Whereas the shape of the low-frequency arcs was relatively independent of operating temperature, the high-frequency arc, due to activation polarization, decreased dramatically as the temperature was increased, in strong agreement with the literature48.
In addition, the impedance, corresponding to activation polarization remained essentially the same for different micro-monolithic SOFCs, while the diffusion polarization was 1.1, 0.75 and 0.45 Ω cm2 for cells with 3, 4 and 7 anode channels, respectively.
