concentration cell

[‚kän·sən′trā·shən ‚sel]
(physical chemistry)
Electrochemical cell for potentiometric measurement of ionic concentrations where the electrode potential electromotive force produced is determined as the difference in emf between a known cell (concentration) and the unknown cell.
An electrolytic cell in which the electromotive force is due to a difference in electrolyte concentrations at the anode and the cathode.

These are 2 kinds of concentration cells. The first is called a salt concentration cell.
According to Revie and Uhlig [4] a more important another kind of concentration cell is the differential aeration cell.
To determine overall system efficiency, one calculates the equilibrium pressure ratio for a gaseous hydrogen concentration cell. This is done with knowledge of the kinetics of both hydrogen reduction and evolution on platinum catalysts, using the Nernst equation.
At this concentration cells became round in shape and also did not stain red with neutral red.
At 0.08 ug/ml concentration cells started becoming round in shape and at 0.1 ug/ml there was clear change in morphology of cells as well as complete deterioration in cells shape (Figure 1) There was also great reduction in the number of cells with increased concentration of chromium (Figure 2).
Author Zito (educator and electrical energy professional) provides a way to make energy portable from non-portable sources and gives engineers practical methods for storing energy and using it at a later time, and covers concentration cells and the potential for using them for grid-scale storage, as well as alternatives to current technologies used for large-scale storage.
There are many innocent people who continue to languish in the concentration cells, he deplored and appealed to the UN Secretary General Ban-ki-Moon to take immediate steps to end human rights violations in occupied Kashmir.
They are also known for creating oxygen concentration cells. Another class of micro-organism, known as anaerobic bacteria, can become active in the absence of oxygen.
These promote corrosion by creating oxygen concentration cells.
At 10 g/ml concentration cells were totally round and they also didn't uptake neutral red and they were appearing transparent in color instead of red (Fig.
