Abstract

A fuel cell tester, which is provided with a plurality of channels and is capable of testing mono-cells or electric piles of a plurality of fuel cells simultaneously, is composed of a flow control unit, a humidifying unit, a signal acquisition unit, a temperature control unit and a discharging unit, etc. The flow control unit includes a plurality of mass flow controllers which are divided into a plurality of groups for the gas distribution of each channel; the humidifying unit is composed of humidifiers and shared constant-temperature oil bath, and the humidifiers are divided into a plurality of groups to humidify each channel; the signal acquisition unit is composed of a stress sensor, a temperature sensor, a humidity sensor and a data acquisition system; the temperature control unit heats the mono-cells or the electric piles to be tested of each channel through a plurality of ways, into which an external-cycle waterway is divided by a constant-temperature water tank; and the discharging unit adopts host plus module type electronic load to meet various test requirements through changing the combination of the modules. The fuel cell tester has the characteristics of accurate gas distribution measurement, precise temperature and pressure control, flexible and convenient test, reasonable layout, reliable performance, etc.

Description

technical field [0001] The invention relates to a fuel cell tester, in particular to a multi-channel proton exchange membrane fuel cell tester, which is suitable for simultaneous activation, tolerance and polarization curve tests of multiple single cells (or stacks). Background technique [0002] Proton exchange membrane fuel cells have the characteristics of high efficiency, energy saving, and low pollution, and are regarded as one of the ideal choices for future automotive energy. Proton exchange membrane fuel cells must undergo performance tests during the research and development process or before they are put into use. The basic test content generally includes polarization curve tests and tolerance tests. The test results can reflect the membrane electrode performance, carbon paper performance, flow field design, battery (stack) assembly is reasonable, etc. A tester generally includes a flow control unit, a humidification unit, a temperature control unit, a signal acqu...
