Abstract

A fuel cell internal temperature-heat flux density distribution measurement insert is a fuel cell internal temperature-heat flux density distribution measurement device, a leakage seam and a rib which are corresponding to a fuel cell flow field plate flow passage and ridge are arranged on a conductive substrate, and a temperature-heat flux density combined measurement sensor is arranged on the rib; the temperature-heat flux density combined measurement sensor is prepared by vacuum evaporation coating method, and comprises five layers of thin films. A leading wire is also prepared by the vacuum evaporation coating method, is used to transmit electrical signals, and extends to the flow field plate edge to form a lead foot by magnifying to facilitate connecting with external connection data acquisition equipment. The fuel cell internal temperature-heat flux density distribution measurement insert realizes the synchronous online measurement of fuel cell internal temperature distribution and heat flux density distribution can be used as a independent component to be arranged in a fuel cell without special transformation of the fuel cell structure, and is wide in range of application, and suitable for a fuel cell flow field plate with a parallel flow passage, a serpentine flow passage, an interleaved flow passage or a flow passage with other shape.
