Morphology
The phrase is compositionally built: 'galvanic' means relating to electricity produced by chemical reactions and 'cell' denotes a unit producing electricity, so together they denote an electrochemical electrical cell. This follows a regular adjective+noun formation common in scientific vocabulary, so a B1 learner who knows both constituents can infer the MWE's meaning.
Etymology
Galvanic cell may come from Luigi Galvani, a scientist who saw frog legs twitch when metal touched them. The word cell means a small unit that makes electricity, so a galvanic cell is like a simple 'battery' that makes electricity from a chemical reaction.
