Hi
Reading Electrochemistry by Hamann [1998, p.237] he says that If a cell has a non offset (no DC) ac signal applied it will operate like "galvanic cell" rather than an "electrolyte cell". I was under the impression that they were the same thing. However, a good old search on Google reveled the following difference:
- Galvanic cell: DeltaG < 0; spontaneous; -DeltaG = maximum electric work output
- Electrolyte cell: DeltaG > 0; non-spontaneous; DeltaG = minimum electric work needed
Does this mean that a Galvanic will produce electrical energy and a electrolyte cell with produce chemical?
Can someone clear this up for me?
Cheers
