Abstract
A method of manufacturing a fuel cell comprising a first step of forming at least a recess on one side of a strengthening frame with a half etching treatment, a second step of jointing a hydrogen permeable membrane to the one side of the strengthening frame with a cladding; and a third step of performing a half etching treatment to a region that is from a region of the other side of the strengthening frame corresponding to the recess to the recess.
Claims10
A method of manufacturing a fuel cell comprising:
- a first step of forming at least a recess portion on one side of a strengthening frame with a half etching treatment;
- a second step of jointing a hydrogen permeable membrane to the one side of the strengthening frame with a cladding;
- and
- a third step of performing a half etching treatment to a region that is from a region of the other side of the strengthening frame corresponding to the recess portion to the recess portion.
