Abstract
A DMFC (direct methanol fuel cell) includes two bipolar plates, a membrane electrode assembly, a bonding layer, and a fuel container base. The bipolar plate is a releasable substrate that includes a releasable copper carrier, a release layer, and a metal foil. The bipolar/MEA assembly is formed by laminating the releasable bipolar, the MEA, and the bonding sheet, peeling off the release carrier, and printing a carbon ink or plating Au.
