Abstract
Provided is a visualization apparatus for a transparent PEMFC using a transparent window having conditions approximating a real PEMFC. More specifically, the present invention improves a fixing frame in consideration of the distribution of pressure applied by the fixing frame, such that the visualization apparatus for a transparent PEMFC has operating conditions approximating the real PEMFC. A visualization apparatus for a transparent PEMFC of the present invention includes: current collector plates each provided at both surfaces of a membrane electrode assembly of a fuel cell and formed with a channel in which reaction gas and products flow; transparent plates provided at an outer surface of the current collector plates; and fixing frames formed with a visualization window for observing the current collector plates and provided at the outer side of the transparent plates, wherein the visualization window is formed in at least two by dividing the single window formed by penetrating through the fixing frame by a bar.
