A silicon-based micro direct methanol fuel cell stack with compact structure and PDMS packaging

This paper presents a micro direct methanol fuel cell (muDMFC) stack implemented by micro fabrication process and PDMS assembly method. The muDMFC stack consists of two muDMFCs stacked one by one with the anode plate shared. Experiment results show that the muDMFC stack generated a power density of 12.71mW/cm
²
, 39.3% higher than that of a single muDMFC, at the cost of only 23% increase in volume.
