Paper-based fuel cell

摘要

The present disclosure provides biological fuel cells comprising a paper-based fuel delivery layer which delivery fuel to the biological anode and cathode via capillary action and/or evaporation. In some embodiments the paper-based fuel delivery layer incorporates an outwardly extending fan-shaped region which enables a constant volumetric flow rate through the cell.

主权项

1. A fuel cell comprising:
at least one paper-based fuel delivery layer (FDL), wherein liquid fuel is able to travel through the FDL via capillary action and/or evaporation; a biological cathode in communication with the FDL, wherein the biological cathode is in fluidic communication with the FDL when fuel is traveling through the FDL; a biological anode in communication with the FDL, wherein the biological anode is in fluidic communication with the FDL when fuel is traveling through the fuel delivery layer; wherein the FDL is positioned between the biological cathode and biological anode.
