1. A decomposition system comprising:
a photodecomposition module and an auxiliary power supply device,
wherein the photodecomposition module comprises:
a plurality of photodecomposition cells;
a posture holder that holds each of the photodecomposition cells in a predetermined posture; and
a pipe structure,
wherein each of the photodecomposition cells decomposes a decomposition liquid with light irradiation, including an anode electrode part and a cathode electrode part in an accommodating part,
wherein the anode electrode part includes a photocatalyst supported on a conductive substrate,
wherein the anode electrode part and the cathode electrode part are immersed in the decomposition liquid in the accommodating part, and
wherein the accommodating part has:
a cylindrical shape;
a first terminal electrically connected to the anode electrode part; and
a second terminal electrically connected to the cathode electrode part, wherein the pipe structure has:
a first wiring line that electrically connects the auxiliary power supply device and the first terminal of each of the photodecomposition cells; and
a second wiring line that electrically connects the auxiliary power supply device and the second terminal of each of the photodecomposition cells, and wherein each of the photodecomposition cells is:
independently attachable to and detachable from the pipe structure; and
electrically connected in parallel to the auxiliary power supply device.
