Abstract

An inspection apparatus of an electrolyte membrane is provided. The apparatus includes a lower supporter having a gas line through which gas flows or a concave portion that stores the gas. An upper supporter is disposed at an upper side of the lower supporter, and includes an opening. A membrane-electrode assembly is disposed between the lower supporter and the upper supporter. An upper cover covers an upper portion of the opening, and is formed with a plurality of partitions. An exhaust port is formed at the upper supporter to exhaust deionized water.

First claim

1 - 10 . (canceled)

11 . An inspection apparatus of an electrolyte membrane comprising:
a lower supporter formed with a deionized water inflow line through which deionized water flows; an upper supporter disposed at an upper side of the lower supporter, and formed with an opening, wherein a membrane-electrode assembly is disposed between the lower supporter and the upper supporter; and an upper cover that covers an upper portion of the opening and is formed with a plurality of partitions.

12 . The inspection apparatus of the electrolyte membrane of claim 11 , wherein a concave portion is formed at a center portion of the lower supporter, and the deionized water inflow line communicates with the concave portion.

13 . The inspection apparatus of the electrolyte membrane of claim 12 , wherein a deionized water exhaust line that communicates with the concave portion is formed at the lower supporter.

14 . The inspection apparatus of the electrolyte membrane of claim 12 , wherein a lower gasket is disposed between the lower supporter and the membrane-electrode assembly.

15 . The inspection apparatus of the electrolyte membrane of claim 12 , wherein an upper gasket is disposed between the upper supporter and the membrane-electrode assembly.

16 . The inspection apparatus of the electrolyte membrane of claim 14 , wherein the lower gasket or the upper gasket includes fluorine or EPDM (ethylene propylene diene M-class) rubber.

17 . The inspection apparatus of the electrolyte membrane of claim 11 , wherein the partitions are disposed with a constant gap along a horizontal direction and a vertical direction.

18 . The inspection apparatus of the electrolyte membrane of claim 11 , wherein a ruler is formed at the partitions.

19 . The inspection apparatus of the electrolyte membrane of claim 11 , wherein: a plurality of upper engagement bores are formed at the upper supporter and a plurality of lower engagement bores are formed at a position that corresponds to the upper engagement bores in the lower supporter.

20 . The inspection apparatus of the electrolyte membrane of claim 12 , wherein a plurality of cover guide bores are formed at the upper cover and a plurality of cover engagement bores are formed at position that corresponds to the cover guide bores in the upper supporter.
