To provide an anode catalyst layer for a fuel cell, which is hard to degrade even if the state of being deficient in hydrogen continues for a long time.SOLUTION: An anode catalyst layer for a fuel cell according to the present invention comprises: electrode catalyst particles; carbon carriers which support the electrode catalyst particles; water electrolysis catalyst particles; a proton-conducting binder; and graphitized carbon. The graphitized carbon is 15 vol.% or more and 70 vol.% or less to a total volume of the electrode catalyst particles, the carbon carriers and the graphitized carbon.SELECTED DRAWING: Figure 1 【課題】本発明は、水素欠乏状態が長時間続いたとしても劣化しにくい燃料電池用アノード触媒層を提供することを目的とする。【解決手段】本発明の燃料電池用アノード触媒層は、電極触媒粒子、前記電極触媒粒子を担持しているカーボン担体、水電解触媒粒子、プロトン伝導性バインダー、並びに黒鉛化カーボンを含み、前記黒鉛化カーボンが、前記電極触媒粒子と前記カーボン担体と前記黒鉛化カーボンとの総体積に対して、１５体積％以上７０体積％以下である、燃料電池用アノード触媒層である。【選択図】図１
