Abstract

In a flow channel plate, in which a first base material and a second base material are joined together so that a recessed portion formed in the first base material is used as a flow channel, an electrode having a recessed and projected shape that encourages a fluid flowing through the flow channel to become a turbulent flow is formed at least on part of a portion corresponding to the flow channel, the portion being part of the second base material, and the second base material is provided with an electrode extraction section that is brought into conduction with the electrode.

First claim

What is claimed is:

1 . A flow channel plate, comprising:
a first base material; and a second base material; the first base material and the second material being joined together and having a recessed portion in at least one of the first base material and the second base material that is defines a flow channel, an electrode having a recessed and projected shape arranged at least on part of a portion corresponding to the flow channel, the portion being part of the second base material, wherein the recessed and projected shape encourages a fluid flowing through the flow channel to become a turbulent flow; and the second base material provided with an electrode extraction section that is brought into conduction with the electrode.

2 . The flow channel plate according to claim 1 , wherein:
the first base material is in a flat-plate shape and the recessed portion is in the first base material; and the second base material is in a flat-plate shape and the recessed and projected shape of the electrode has a plurality of ridges, each of which has a predetermined angle with respect to a liquid transfer direction of the flow channel, and has an electrode film among the plurality of ridges.

3 . The flow channel plate according to claim 2 , wherein each of the plurality of ridges is in a V-shape that has a vertex oriented toward an upstream of the fluid flowing through the flow channel.

4 . The flow channel plate according to claim 3 , wherein, a direction perpendicular to a surface of the second base material defines a height direction of the flow channel, and the plurality of ridges are arranged so that a height of the plurality of ridges falls within a range from one-third to two-thirds of the height of the flow channel in the height direction.

5 . The flow channel plate according to claim 1 , wherein:
the electrode extraction section has an external electrode on a surface of the second base material, the surface being on an opposite side to a surface on the same side as the flow channel, and has a through-electrode that passes through the second base material from the surface on the opposite side to the surface on the same side as the flow channel; and the external electrode is electrically connected to the electrode through the through-electrode.

6 . The flow channel plate according to claim 1 , wherein the electrode and electrode extraction section comprise a printed conductive paste that includes carbon.
