In the electrochemical element, a plate-like support includes an internal passage through which a first gas flows, a gas-permeable portion, and an electrochemical reaction portion in which a film-like electrode layer, a film-like electrolyte layer, and a film-like counter electrode layer are stacked so as to entirely or partially cover the gas-permeable portion. The internal passage includes a plurality of auxiliary passages through which the first gas flows in a predetermined flowing direction, and a distribution portion provided on the upstream side of the plurality of auxiliary passages in the flowing direction of the first gas. The plate-like support includes a supply structure that is located between the distribution portion and the auxiliary passages in the flowing direction. The first gas is temporarily stored in the distribution portion and supply of the first gas from the distribution portion to the plurality of auxiliary passages is limited.

Electrochemical element, electrochemical module, electrochemical device, and energy system

A position detection device includes a first member, a second member, a plurality of detected components, a detector group, and a controller. The second member is opposed the first member and is configured to move relative to the first member in a specific direction. The plurality of detected components are disposed on the first member and faces the second member. The detector group is disposed on the second member and includes a plurality of detectors configured to detect the plurality of detected components. The controller is configured to detect a relative position of the second member relative to the first member based on a detection pattern in which detection results of the plurality of detectors are arranged in a row.

Position detection device

A flash unit includes a flash device operable to emit flash, a storage member operable to store the flash device, a cover with which the storage member is covered from above, and to which the flash device is attached, a first link member that is turnably connected to the storage member at one end and turnably connected to the cover at another end, and a retaining member. The first link member is stored in the storage member in a lying state when the flash device is not used, and the first link member is adapted to turn about a connection portion of the first link member and the storage member to take a raised up state in which a connection portion of the first link member and the cover is located above the connection portion of the first link member with the storage member when the flash device is used, the cover can turn about the connection portion with the first link member to take the raised up state in which the flash device is raised higher than the connection portion with the first link member, and the retaining member retains the first link member in the raised up state.
