A bendable and compactdevice for low-power application

[摘要] In this work we present a novelmodel of a membraneless microfluidic fuel celldevice based on adhesive polyester film fabricated by a non-sophisticated technique at room temperature and reached high performance. This concept overcomes the concerns about the reliability, versatility and weight of fuel cell devices for portable energy applications.Current densities until500 mA cm-2and power densities about 90mW cm-2were achieved using formic acid as fuel and air and dissolved oxygen as oxidant.
