Galvanic Cell Definition Diagram and Working
· The cell is named "galvanic" after its inventor the physicist Luigi Galvani. In 1780 Galvani demonstrated that when two different metals are connected to each other at one end while the other ends are connected by the legs of a frog the legs contract indicating the flow of electricity. He called his absurd apparatus "animal circuitry".

The Experiment That Shocked the World Helix Magazine
Established pillars were under attack across the Western world. It was the late 1700s and the United States had just declared independence. France was rapidly heading towards a bloody revolution. Industrialization was beginning to reshape society. And amidst the chaos an obscure Italian physiologist stepped outside to do a science experiment.

· Degradation is one of the most important issues in solid oxide electrolysis cells (SOECs). The lowest long-term degradation reported in the literature for SOEC under practical operation is about 1.7 /1000 h during 3600 h at −1 A/cm 2 which is twice the degradation of similar cells under fuel cell operation.

In a galvanic cell there are two half-cells. Each half-cell contains an electrode in an electrolyte. The separation is necessary to prevent direct chemical contact of the oxidation and reduction reactions creating a potential difference. The electrons released in the oxidation reaction travel through an external circuit (and do work) before being used by the reduction reaction.
