Abstract

Abstract: The new concept of a hook-and-loop tape-based membraneless device constructed on adhesive polyester film, which is fabricated using non-sophisticated and inexpensive fabrication techniques at room temperature, is presented. This concept overcomes the concerns about the reliability, versatility, weight, cost, lifetime and high performance of microfluidic fuel cell devices to satisfy the needs of portable energy applications. Current densities from 150 to 600 mA cm −2 and power densities from 40 to 132 mW cm −2 were achieved by varying the formic acid concentration, flow rates and by using air and dissolved oxygen as an oxidant.
