This paper reports a novel assembly method using multi-layer bonding technique for micro direct methanol fuel cells (mu DMFCs) and their stacks. The new approach shows considerable merit on maneuverability and reliability, and is beneficial to decreasing the internal resistance of the mu DMFC. The prototype of mu DMFC assembled generates a high power density of 20.29 mW/cm(2) and a power of 45.6 mW with high methanol concentration at room temperature. Benefiting from the assembly process, a new mu DMFC 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.
