To inhibit the scattering of Mn contained in a specific member into a fuel chamber, the specific member constituting a gas passage where gas supplied to a fuel electrode flows.SOLUTION: An electrochemical reaction module includes an electrochemical reaction device including an electrochemical reaction single cell that includes an electrolyte layer containing a solid oxide, and an air electrode and a fuel electrode facing each other with the electrolyte layer sandwiched therebetween, a specific gas passage where gas supplied to a fuel electrode flows being formed in the electrochemical reaction module. An oxide film is formed on at least part of a surface of a specific member that defines the specific gas passage and that is a Mn-containing member, the oxide film facing the specific gas passage and including a specific compound that is a compound of Mn and a specific element of at least one element selected from among Si, Al, Ti and S.SELECTED DRAWING: Figure 8 【課題】燃料極に供給されるガスが流通するガス流路を構成する特定部材に含まれるＭｎが燃料室に飛散することを抑制する。【解決手段】電気化学反応モジュールは、固体酸化物を含む電解質層と、電解質層を挟んで互いに対向する空気極および燃料極と、を含む電気化学反応単セルを有する電気化学反応装置を備え、かつ、燃料極に供給されるガスが流通する特定ガス流路が形成されている。特定ガス流路を画定すると共にＭｎを含む部材である特定部材の表面の少なくとも一部に、特定ガス流路に面し、かつ、Ｍｎと、Ｓｉ，Ａｌ，ＴｉおよびＳから選択される少なくとも１つの元素である特定元素と、の化合物である特定化合物を含む酸化被膜が形成されている。【選択図】図８
