Abstract:
1. A method for fabricating a membrane for an ion-exchange electrochemical cell, said method comprising: positioning a negative tone photoresist substrate with a girth; predefining polygonal ion passage channel dimensions; positioning a photon radiation source proximate to said substrate; linearly actuating said substrate with respect to said radiation source to radiate a first linear row through said girth of said substrate; linearly actuating said substrate with respect to said radiation source to radiate a second linear row, substantially parallel to said first linear row, through said girth of said substrate; linearly actuating said substrate with respect to said radiation source to radiate at least two boundary rows, contacting said first linear row and said second linear row, through said girth of said substrate; and dissolving unradiated substrate portions.
