An electrochemical module including: a stack obtained by stacking, in a predetermined stacking direction, a plurality of electrochemical elements having a configuration in which an electrode layer, an electrolyte layer, and a counter electrode layer are formed along a substrate, via an annular sealing portion through which first gas that is one of reducing component gas and oxidative component gas flows; a container that includes an upper cover for pressing a first flat face in the stacking direction of the stack and a lower cover for pressing a second flat face on a side opposite to the first flat face, the stack being sandwiched between the upper cover and the lower cover; and a pressing mechanism that presses a portion to which the annular sealing portion is attached against the container in the stacking direction.

Electrochemical module, electrochemical device, and energy system

A small-size and light-weight electrochemical module in which, when a stack expands the stack can be clamped appropriately. The electrochemical module includes: an electrochemical element stack obtained by stacking, in a predetermined stacking direction, a plurality of electrochemical elements having a configuration in which an electrolyte layer, and a first electrode and a second electrode that are respectively arranged on two sides of the electrolyte layer, are formed along a substrate; an elastic plate-like member arranged along at least one of a first flat face and a second flat face of the electrochemical element stack; and a clamp that includes a first clamping portion extending along the first flat face and a second clamping portion extending along the second flat face and clamps the electrochemical element stack via the plate-like member.

Electrochemical module, method for assembling electrochemical module, electrochemical device, and energy system

An electrochemical element including a plate-like support provided with an internal passage therein. The plate-like support includes a gas-permeable portion through which gas is permeable between the internal passage and the outside of the plate-like support and an electrochemical reaction portion that is formed by stacking at least a film-like electrode layer, a film-like electrolyte layer, and a film-like counter electrode layer in the stated order in a predetermined stacking direction on an outer face of the plate-like support so as to entirely or partially cover the gas-permeable portion. A first gas, that is one of reducing component gas and oxidative component gas, flows through the internal passage, and the internal passage is provided with a turbulence forming body that forms a turbulence state of the first gas.

A fluid processing apparatus having a plurality of processing spaces (S) includes a plurality of containers (B) juxtaposed in a direction to each other forming processing spaces (S) respectively therein. Pressing means (H) is provided for pressing the containers (B) as juxtaposed from opposed sides thereof in the juxtaposing direction of the containers. Each container (B) includes a pair of container-forming members () disposed in the juxtaposing direction and having peripheral portions thereofjoined and welded to each other. At least one of the pair of container-forming members () is in the form of a dish-like member having a peripheral portion used as a joining margin and a bulging central portion.
