Abstract
Disclosed is a jig for surface treatment of a separator which is used to partially form a coating layer on a surface of the separator in which each land and each channel are alternately and repeatedly formed on one side and the other side according to a concavo-convex shape. In particular, the jig includes: a first jig which has a first plate part disposed on the one side of the separator and first mask parts protruding from the first plate part to cover an inner surface of one side-channel; and a second jig that has a second plate part disposed on the other side of the separator and second mask parts protruding from the second plate part to cover an inner surface of the other side-channel.
Claims3
A jig for surface treatment of a separator of a fuel cell, where the jig is used to partially form a coating layer on a surface of the separator in which each land and each channel are alternately and repeatedly formed on a first side and a second side corresponding to a concavo-convex shape, the jig comprising:
- a first jig comprising:
- a first plate part disposed on the first side of the separator and spaced apart from a one side-land of the separator in a direction of the first side;
- and
- first mask parts that protrude from the first plate part in a direction of a one side-channel of the separator to cover an inner surface of the one side-channel;
- and
- a second jig comprising:
- a second plate part disposed on the second side of the separator and spaced apart from an other side-land of the separator in a direction of the second side;
- and
- second mask parts that protrude from the second plate part into a direction of an other side-channel of the separator to cover an inner surface of the other side-channel,
- wherein:
- the first jig is formed in a shape corresponding to the concavo-convex shape of the first side of the separator, and the first plate part and the first mask parts are integrally formed using a non-conductive material,
- the second jig is formed in a shape corresponding to the concavo-convex shape of the second side of the separator, and the second plate part and the second mask parts are integrally formed using the non-conductive material,
- the first mask parts of the first jig are bent into a shape corresponding to the one side-channel of the separator to be in close contact with the inner surface of the one side-channel,
- the second mask parts of the second jig are bent into a shape corresponding to the other side-channel of the separator to be in close contact with the inner surface of the other side-channel,
- the first plate part of the first jig is formed to be narrower than a width of the one side-land of the separator, and
- the second plate part of the second jig is formed to be narrower than a width of the other side-land of the separator.
