Claims (6)

1. Fastoxidbrændselscelle (10), der omfatter: et brændselscellehovedlegeme, der indbefatter et katodelag (141), et fastelektrolytlag (143) og et anodelag (144), og som har en strømgenereringsfunktion; en konnektor (110), der er placeret til at vende ind mod ét elektrodelag af katodelaget (141) og anodelaget (144); strømaftagere (147), der er placeret mellem det ene elektrodelag (141, 144) og konnektoren (110), og som er i kontakt med en overflade af det ene elektrodelag (141, 144) og en overflade af konnektoren (110), hvilke overflader vender ind mod hinanden for derved elektrisk at forbinde det ene elektrodelag (141, 144) og konnektoren (110); og riller (145) tilvejebragt i en del af en overflade af det ene elektrodelag (141, 144), hvilken overflade er placeret på siden, hvor det ene elektrodelag (141, 144) er i kontakt med strømaftagerne (147), hvor delen af overfladen ikke er i kontakt med strømaftagerne (147), hvor rillerne (145) strækker sig i to retninger, der hælder i forhold til en retning for en strømningsbane af en oxiderende gas tilført katodelaget (141) eller en retning for en strømningsbane for en brændselsgas tilført anodelaget (144), kendetegnet ved, at strømaftagerne (147) er anbragt i et gitter set fra oven.
2. Fastoxidbrændselscelle (10) ifølge krav 1, hvor overfladen af det ene elektrodelag (141, 144), der er i kontakt med strømaftagerne (147), har en aritmetisk middel ruhed Ra, der er større end 0,3 pm.
3. Fastoxidbrændselscelle (10) ifølge krav 1 eller 2, hvor overfladen af det ene elektrodelag (141, 144), der er i kontakt med strømaftagerne (147), har en aritmetisk middel bølgethed Wa, der er mindre end 0,3 pm.
4. Fastoxidbrændselscelle (10) ifølge et hvilket som helst af kravene 1 til 3, hvor hver strømaftager (147) er fremstillet af et materiale, der er det samme som konnektorens (110) materiale, således at hver strømaftager (147) er forenet med konnektoren (110).
5. Fastoxidbrændselscelle (10) ifølge et hvilket som helst af kravene 1 til 4, hvor rillernes (145) to udstrækkende retninger har hældningsvinkler på ±45° i forhold til retningen af strømningsbanen for den oxiderende gas eller brændselsgassen.
6. Fastoxidbrændselscelle (10) ifølge et hvilket som helst af kravene 1 til 5, hvor, set fra oven, strømningsbaner af den oxiderende gas tilført katodelaget (141) eller strømningsbaner af brændselsgassen tilført oxidlaget (144) strækker sig i to strømningsbaneretninger mellem de strømaftagerne (147), der er anbragt i gitteret.
