Title
(JA) 高温燃料電池の運転方法
Abstract
(JA)

本発明は、通常の電力発生モードにおいては液体燃料(B)、好ましくはディーゼルが供給され、上流で接続された液体燃料の改質器をアノード側に備えた高温燃料電池(1)について、高温アノード排ガスの少なくとも一部を再循環ライン(3)を通じてアノード循環流路に再循環し、改質器(2)の上流に接続されている圧縮器(4)の上流で液体燃料(B)を高温アノード排ガスに噴射または注入し、液体燃料を改質するのに必要な量の空気をアノード排ガスと燃料との混合物に加える高温燃料電池(1)の運転方法に関するものである。本発明によると、通常運転モードから電力を発生させない待機運転モードに切り替える際に液体燃料(B)と空気(L)の供給を停止してアノード循環流路内のガス混合物を永続的に循環させ、待機運転が始まると、高温燃料電池(1)内の付着物や不純物を除去するために所定量の空気をアノード循環流路に供給する。
