Abstract

A solid electrolyte type fuel cell, comprising a branch flow rate regulating part (12) for branching air between an air supply source (9) and a heat exchanger (10), leading the branched air to a heat recovery passage (11), and regulating the branched air amount to properly control the flow of a fluid flowing to a flow passage for heat recovery to the total of the flow.

Description

technical field [0001] The present invention relates to a solid electrolyte fuel cell configured by housing a solid electrolyte fuel cell stack in a storage container. Background technique [0002] Conventionally, a fuel cell has been proposed (see Patent Document 1 and Patent Document 2) in which a heat recovery passage for recovering heat lost from the battery module is provided around the battery module, wherein the battery module The inside of the stack includes: a cell stack that generates electricity from fuel gas and oxygen-containing gas; and a combustion unit that burns excess fuel gas and oxygen-containing gas from the cell stack in contact with each other. [0003] The solid electrolyte fuel cell described in Patent Document 1 is constituted by forming a fluid channel between a high-temperature heat insulating material and a low-temperature heat insulating material surrounding the fuel cell stack, and supplying air to the air inlet port of the fuel cell stack thro...
