Abstract
Despite the significant research in micro fuel cells, miniaturizing a whole fuel cell system to below a few millimeters did not appear feasible until very recently, because ancillary parts (e.g. external pump, gas separator) are needed to complete a self-standing system. Building on the recently discovered self-pumping fuel cell free of the ancillary parts, here we design and test new self-pumping fuel cell architecture free of the membrane electrode assembly (MEA). Benefiting from the selectivity of catalysts on each electrode under slow flow rates, we find that the device can be run in a mixed stream instead of the two streams of unmixed laminar flows of fuel and oxidant, greatly simplifying the design. Proof-of-concept device verifies the mechanism of embedded fuel pumping and CO2 degassing, while producing 8 mW/cm2 of peak power density. ©2010 IEEE.
