An electrolyte membrane for a fuel cell, comprising:
- a sheet part having a plate shape with a predetermined length and width, wherein the sheet part comprises a non-reaction area in a peripheral portion and a reaction area in a center portion;
- and
- a reinforcing part positioned on at least one of longitudinal ends of the reaction area and having a predetermined thickness,
- wherein a cross section in the longitudinal direction of the reinforcing part has a streamline curved shape such that a thickness of the cross section is reduced toward both ends from a center portion thereof.
A method of manufacturing an electrolyte membrane for a fuel cell, comprising:
- preparing a sheet part having a plate shape with a predetermined length and width, wherein the sheet part comprises a non-reaction area in a periphery portion and a reaction area in a center portion;
- and
- forming a reinforcing part having a predetermined thickness on at least one of longitudinal ends of the reaction area,
- wherein a cross section in the longitudinal direction of the reinforcing part has a streamline curved shape such that a thickness of the cross section is reduced toward both ends from a center portion thereof.
An electrolyte membrane for a fuel cell, comprising:
- a sheet part having a plate shape with a predetermined length and width,
- wherein the sheet part comprises a non-reaction area in a peripheral portion and a reaction area in a center portion;
- and
- a reinforcing part positioned on at least one of longitudinal ends of the reaction area and having a predetermined thickness,
- wherein a distance from one end of the reaction area to one end of the reinforcing part disposed on the reaction area ranges from about 2 cm to about 5 cm.
