A finite element model for mixed potential sensors
Abstract. Many studies are dealing with the behavior of mixed potential sensors. However, a quantitative description of the processes leading to the sensor signals has not yet been carried out. This paper describes a first approach to address the question to what extent a mixed potential sensor can be modelled in a finite element model.

Mixed Potential Theory
Corrosion inhibition. Jeremy Moloney, ... Thunyaluk Pojtanabuntoeng, in Flow Assurance, 2022. 9.7.2.2 Corrosion potential measurement. The mixed potential theory defines the corrosion potential as a potential at which the cathodic current equals the anodic current. The current at this potential is the corrosion current. Thus changes in cathodic or anodic …

6. Discussion. The typical open-circuit voltage of a DMFC is between 0.8 and 0.6 V.With the theoretical OCV in the order of 1.2 V, the total voltage loss at zero current is thus between 400 and 600 mV.As discussed above, the mixed potential due to poor oxygen transport gives 150–200 mV at the cell current of about 10 mA cm −2; at zero …

The PPR potential-based model for cohesive fracture is verified by simulating a mixed-mode fracture problem, the mixed-mode bending (MMB) test. The MMB test was developed by Reeder and Crews (1990) in order to investigate the fracture toughness variation with respect to the mode mixity. The test has been standardized by ASTM (2006).
