PROBLEM TO BE SOLVED: To provide a phosphoric acid collector capable of preventing early clogging of a filter and decreasing the replacing frequency of the filter. SOLUTION: This phosphoric acid collector consists of a cylinder 2 forming a path for passing an oxidizing agent gas exhausted from an oxygen electrode of a fuel cell having a phosphoric acid electrolyte and a filter 41 installed in the cylinder 2 and made of a metal easy to react with phosphoric acid. The filter 41 has the surface in which an oxidizing agent gas inflow side edge surface does not perpendicularly cross to gas flow. The phosphoric acid collector has a groove 51 on the oxidizing agent gas inflow side of the filter 41. |
