Galvanic pile array in solid oxide fuel battery power generating system

The invention provides a galvanic pile array in a solid oxide fuel battery power generating system. The galvanic pile array comprises a supporting body and a galvanic pile group, wherein the supporting body is in a layered structure and comprises one or more than two layers of supporting units; on each layer of supporting unit, a plurality of single galvanic piles are sequentially arranged to form a galvanic pile group, and each single galvanic pile is horizontal. The galvanic pile array is simple, compact and firm, and is favorable for system integration.
