An assembly of electrically interconnected electrolytic cells supplied by a source of direct current power is known as what?

The term that accurately describes an assembly of electrically interconnected electrolytic cells powered by direct current is "electrolytic stack." This term specifically refers to multiple electrolytic cells that are connected in series or parallel to enhance the overall electrochemical reaction efficiency within various applications, such as electrolysis processes, fuel cells, or energy storage systems.

A battery bank typically refers to a collection of batteries used to store energy, while a cell line might describe an arrangement or series of cells but does not specifically connote the electrolytic processes involved. A power module often refers to a compact assembly of power components and circuits without the specificity required to identify an electrolytic configuration. Therefore, "electrolytic stack" is the most precise term in this context reflecting the interconnected electrolytic cells linked by a direct current power source.
