摘要：

Ammonia-borane (NH3BH3), as a source of protide (H-), is initially proposed to release its energy through a fuel cell (direct ammonia-borane fuel cell, DABFC). Cell performance has been elucidated in a 25 cm(2) laboratory cell constructed with an oxygen cathode and an ammonia-borane solution fed anode, where the catalyst layers are made of Vulcan XC-72 with 30 wt.% Pt. The potential is 0.6 V at the current density of 24 mA cm(-2), corresponding to power density >14 mW cm(-2) at room temperature. The direct electron transfer from protide (H-) in NH3BH3 to proton (H+) has been further proved by the open circuit potential and the cyclic voltammetry results, which show the possibility of improvement in the performance of DABFC by, for example, exploring new electrode materials.
