Fuel cell internal temperature-heat flux density distribution measurement insert

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.

AI Technical Summary

Benefits of technology

This new technology allows us to accurately determine both the amount of thermal energy (the rate at which it releases or absorbs) inside each part of an individual fuel cell without having to remove any parts from its environment during testing. It uses specialized equipment that measures this distributed data on real world conditions while keeping them stable over long periods of use. Overall, these technical improvements make better understanding how different types of fuels behave differently under specific environmental factors improving their overall efficiency and reliability within power systems.

Problems solved by technology

This patented describes various technical problem addressed in the patents: how to efficiently convert chemical reactions into electrical power through fuel cells that contain tiny electronic components called molecules (molecular fuels) at specific locations within their interior space. Existing techniques involve embedding small devices like microelectronic elements near certain points where there may occur localized high temperatures caused by the combustion process itself. These conventional approaches often result in variations in temperature distributions throughout the entirety of the system, making accurate analysis challenges even more complex than desired.
