Abstract
(EN)
A fuel cell (10) according to the present invention is provided with a supporting substrate (4), one or more power generation element parts (5), one or more first gas flow channels (43) and one or more second gas flow channels (44). The power generation element part (5) is arranged on the supporting substrate (4). The first and second gas flow channels (43, 44) extend within the supporting substrate (4) from a base end part (101) toward a front end part (102), while being in communication with each other at the front end part (102). The sum of the cross-sectional areas of the one or more first gas flow channels (43) is smaller than the sum of the cross-sectional areas of the one or more second gas flow channels (44).
(FR)
Une pile à combustible (10) selon la présente invention comporte un substrat de support (4), une ou plusieurs parties d'élément de production d'énergie (5), un ou plusieurs premiers canaux d'écoulement de gaz (43) et un ou plusieurs seconds canaux d'écoulement de gaz (44). La partie d'élément de production d'énergie (5) est disposée sur le substrat de support (4). Les premier et second canaux d'écoulement de gaz (43, 44) s'étendent à l'intérieur du substrat de support (4) à partir d'une partie d'extrémité de base (101) vers une partie d'extrémité avant (102), tout en étant en communication l'un avec l'autre au niveau de la partie d'extrémité avant (102). La somme des aires de section transversale de l'un ou plusieurs premiers canaux d'écoulement de gaz (43) est inférieure à la somme des aires de section transversale de l'un ou plusieurs seconds canaux d'écoulement de gaz (44).
(JA)
燃料電池セル(10)は、支持基板(4)と、少なくとも1つの発電素子部(5)と、少なくとも1つの第1ガス流路(43)と、少なくとも1つの第2ガス流路(44)とを備えている。発電素子部(5)は、支持基板(4)上に配置される。第1及び第2ガス流路(43,44)は、支持基板(4)内を基端部(101)から先端部(102)に向かって延び、先端部(102)において互いに連通している。少なくとも1つの第1ガス流路(43)の断面積の合計値は、少なくとも1つの第2ガス流路(44)の断面積の合計値よりも小さい。
