Gas decomposition apparatus and method for decomposing gas

摘要

[Object] To provide a gas decomposition apparatus and a gas decomposition method in which no safety problems occur in spite of the application of a relatively high voltage between an anode and a cathode for the purpose of decomposing odorous gases of many types.;[Solution] A catalytic electrode layer 6 that contains a catalyst and is porous; a counter electrode layer 7 that forms a pair with the catalytic electrode; and an electrolyte layer 15 that is sandwiched between the catalytic electrode and the counter electrode and has ion conductivity are included. The catalyst is held by the catalytic electrode in the form of being carried by a carrier containing a conductive material or the catalyst is directly carried by the catalytic electrode. A conductive material in the catalytic electrode, the conductive material being in contact with the catalyst, is not a noncovalent carbon material.

1. A gas decomposition apparatus comprising:
a decomposition-side electrode being a porous electrode having a gas inlet into which gas containing a component to be decomposed is introduced; a counter electrode that forms a pair with the decomposition-side electrode and is porous; and an electrolyte sandwiched between the decomposition-side electrode and the counter electrode, wherein a portion of the decomposition-side electrode, the portion being in contact with the electrolyte, is composed of a material that is inert to water.
