Method and device for separating electrodes of a membrane electrode assembly of a fuel cell

Abstract

The present invention discloses a method for separating electrodes of a membrane electrode assembly of a fuel cell from the decal transfer film and a device for separating the electrodes. Specifically, by the freezing method for freezing the sample on the surface of deionized water, during the separation process of the electrode, only the electrode was separated from the decal transfer film coated with the electrode without any damage. , thus preventing the waste of expensive MEA. The mechanical properties of the original electrode can thus be rapidly quantified in advance, thereby significantly reducing the evaluation period for long-term durability during the development of MEA with significant durability.

Description

technical field [0001] The invention relates to a method and device for separating electrodes of a membrane electrode assembly of a fuel cell. In particular by said separation method comprising freezing the electrode sample on the surface of deionized water, said electrode can be separated from the decal transfer film coated with this electrode without any visible damage. Thus, by separating the electrodes from the decal transfer film instead of separating the electrodes from the MEA (membrane electrode assembly), when the electrodes themselves are separated from the MEA, the expensive MEA may not be damaged and wasted. In addition, the mechanical properties of the electrodes can be quickly quantified in advance, thus, the long-term durability evaluation period during the formation of an improved durability MEA can be greatly reduced. Background technique [0002] In general, a polymer electrolyte membrane fuel cell (PEMFC: polymer electrolyte membrane fuel cell) has been w...

Problems solved by technology

[0011] However, these conventional methods of layer separation may have problems such that the object to be separated may be damaged during the layer separation process, or the layers may not be completely separated

Therefore, these methods cannot be used to separate the pristine electrodes for the fuel cell MEA, in particular, they cannot be used to completely separate the pristine electrodes of the fuel cell MEA for the quantification of the mechanical properties due to damage during the separation process.
