Abstract

The invention discloses a fuel cell temperature control and testing system, which comprises a fuel cell, two water cavities, a constant temperature water tank, two collector plates, several temperature sensors, several semiconductor refrigeration devices, a driving circuit, a reversing circuit, a temperature A controller and a data acquisition system; the invention also discloses a fuel cell temperature control and testing method. The invention can uniformly distribute the surface temperature of the fuel cell, shorten the response time of temperature control, and widen the temperature control range.

Description

technical field [0001] The invention relates to a temperature control and test system and method, in particular to a fuel cell temperature control and test system and method. Background technique [0002] In the fields of fuel cells, energy and electronics, it is necessary to achieve precise temperature control of components, fast temperature control range, and fast temperature response. Taking fuel cells as an example, the thermal management of fuel cells is one of the important issues affecting their engineering applications. One of the main tasks of battery thermal management is temperature control. The commonly used methods or means of battery temperature control are: heating rod (pad), air cooling, circulating water and constant temperature box. The main disadvantages of the above methods are: the temperature control method of the fuel cell is mostly a convective heat transfer method, and the temperature distribution is uneven, which makes the repeatability of the bat...
