Title
(EN) UNIT CELL OF FUEL CELL
(FR) PILE UNITAIRE DE PILE À COMBUSTIBLE
(JA) 燃料電池単セル
Abstract
(EN)
This unit cell of a fuel cell is provided with: a fuel cell unit formed by sequentially stacking an anode, an electrolyte layer, and a cathode; a separator; and a power collection auxiliary layer disposed between the cathode of the fuel cell unit and the separator, wherein the separator has a protrusion in contact with the power collection auxiliary layer and forms a gas flow channel between the separator and the power collection auxiliary layer. Further, at least a portion of a plane-direction end of the cathode is configured to extend outward beyond a plane-direction end of the power collection auxiliary layer.
(FR)
L'invention concerne une pile unitaire d'une pile à combustible qui est pourvu : d'une unité de pile à combustible formée par empilement séquentiel d'une anode, d'une couche d'électrolyte et d'une cathode ; d'un séparateur ; d'une couche auxiliaire de captage d'énergie disposée entre la cathode de l'unité de pile à combustible et le séparateur, le séparateur ayant une saillie en contact avec la couche auxiliaire de captage d'énergie et formant un canal d'écoulement de gaz entre le séparateur et la couche auxiliaire de captage d'énergie. En outre, au moins une partie d'une extrémité dans la direction plane de la cathode est configurée pour s'étendre vers l'extérieur au-delà d'une extrémité dans la direction plane de la couche auxiliaire de captage d'énergie.
