Yield and open-circuit-voltage enhancement of 0.36 mm2 solid-state CMOS-compatible glucose fuel cells by using repeated separator coating.

Fabrication of a 0.36 mm² (0.6 mm × 0.6 mm) solid-state CMOS-compatible glucose fuel cell, which delivers 12% yield and a highest reported open circuit voltage (OCV) of 370 mV, is presented. The introduction of repeated separator coating helps avoid electrical short-circuiting between the anode and cathode of the fuel cell, resulting in a higher yield as compared to that when the conventional single coating is used. Higher yield allows improvement in the value of peak OCV. The measurement results show an OCV of 370 mV and a 12% yield with a 30 mM glucose solution. [ABSTRACT FROM AUTHOR]
