Abstract
In a metal support mostly used for a metal-supported solid oxide fuel cell (SOFC), a SOFC system that improves the power generation efficiency by allowing a gas to smoothly flow into or flow out from the through-holes is achieved. A metal support is formed in a plate shape as a whole and has a plurality of through-holes penetrating from a front surface on which an electrode layer is provided to a back surface, and the metal support has inclined through-holes, as the through-holes each of which has a central axis inclined with respect to a thickness direction.

A metal support that is formed in a plate shape as a whole, comprising:
- a plurality of through-holes penetrating from a front surface on which an electrode layer is provided to a back surface,
- wherein the metal support has inclined through-holes, as the through-holes, each of which has a central axis inclined with respect to a thickness direction,
- wherein a gas flow channel through which a gas supplied to and received from the electrode layer flows is provided along the back surface of the metal support,
- wherein in the gas flow channel, gas flows along a gas flow direction from an inlet provided at an upstream end to an outlet provided at a downstream end, and
- as the inclined through-holes, the metal support has a first inclined through-hole of which an opening on a front side of the metal support is positioned at further downstream of the gas flow channel in a gas flow direction than an opening on a back side of the metal support.
