This paper reports a novel assembly method using multi-layer bonding technique for micro direct methanol fuel cells (¦ÌDMFCs) and their stacks. The new approach shows considerable merit on maneuverability and reliability, and is beneficial to decreasing the internal resistance of the ¦ÌDMFC. The prototype of ¦ÌDMFC assembled generates a high power density of 20.29 mW/cm² and a power of 45.6 mW with high methanol concentration at room temperature. Benefiting from the assembly process, a new ¦ÌDMFC tri-cell stack with an expandable cell amount is designed, fabricated and assembled, which has a maximum power of 86.92 mW with 2 M methanol concentration at room temperature. Moreover, this work presents a promising strategy for the assembly of microfluidic devices with laminated structures.
