Imposed currents in galvanic cells
We analyze the steady-state behavior of a general mathematical model for reversible galvanic cells, such as redox flow cells, reversible solid oxide fuel cells, and rechargeable batteries. We consider not only operation in the galvanic discharging mode, spontaneously generating a positive current against an external load, but also operation in two modes which require a net input of electrical e...

متن کاملGalvanic Coupling of Direct Currents in Transmission Grids and Its Effects on Power Transformers
Different stress factors impact power transformers during service. In most cases, the effects of additional direct current (DC) components are not taken into consideration. Nevertheless, this contribution considers DC or quasi-DC components which occur in the German transmission grid (400 kV level). Current measurements are therefore performed at several grounded star points of grid coupling po...
متن کاملHomogenization of a Nonlinear Elliptic Boundary Value Problem Modeling Galvanic Currents
We study a nonlinear elliptic boundary value problem arising from electrochemistry in the study of heterogeneous electrode surfaces. The boundary condition is of exponential type (Butler–Volmer) and has a periodic structure. We find a limiting or effective problem as the period approaches zero, along with a first order correction. We establish convergence estimates and provide numerical experim...
متن کاملFuture Large-Scale Memristive Device Crossbar Arrays: Limits Imposed by Sneak-Path Currents on Read Operations
Passive crossbar arrays based upon memristive devices, at crosspoints, hold great promise for the future high-density and non-volatile memories. The most significant challenge facing memristive device based crossbars today is the problem of sneak-path currents. In this paper, we investigate a memristive device with intrinsic rectification behavior to suppress the sneak-path currents in crossbar...
