PURPOSE:To equalize the temperature distribution during the operation of a molten-salt fuel cell, and enable the operational temperature of the fuel cell to be regulated by providing a battery frame with flow paths, which are used for supplying and exhausting both a heating medium and a refrigerant and which can perform cooling of either external heating or self-heating. CONSTITUTION:The central part of a battery frame 1 has a hollow space which is formed by a fuel chamber 2, current-collecting projections 3, and refrigerant-and-heating-medium paths 4 which also serve as current-collecting projections. In the hollow center of the battery frame 1, refrigerant-and-heating-medium flow paths 7 each extending from a refrigerant-and-heating- medium inlet 5 to a refrigerant-and-heating-medium outlet 6 are provided. The peripheral part 8 of the battery frame 1 is provided with fuel-inlet-side paths 9 and fuel-outlet-side paths 10 which are connected to the fuel chamber 2, as well as oxidant-inlet-side paths 11 and oxidant- outlet-side paths 12 which are connected to an oxidant chamber 13 provided on the back surface of the battery frame 1. In the central part of the battery frame 1, there are the oxidant chamber 13, oxidant-chamber-side current-collecting projections 14 and oxidant-chamber-side refrigerant-and-heating-medium paths 15, and refrigerant-and-heating-medium flow paths 7 each extending from an oxidant-chamber-side refrigerant-and-heating-medium inlet 16 to an oxidant- chamber-side refrigerant-and-heating-medium outlet 17 are provided. Here, these members cross perpendicularly to the current-collecting projections 3, the refrigerant-and-heating-medium paths 4 and the like which are provided on the fuel chamber side. |
