中文摘要：

自从它是为 H ₂ 生产的一个方便方法，蚁的酸(FA ) 除氢作用吸引了很多注意。在这个工作，我们设计了一自食其力燃料房间系统，在 H，从 FA 的 ₂ 被供应进燃料房间，和从燃料房间的 exhaust 热支持了 FA 除氢作用。以便认识到系统，我们综合了高度活跃、选择的同类的催化剂 IrCp *Cl ₂ 为 FA 除氢作用的 bpym。为 FA 除氢作用的催化剂的周转频率(TOF ) 象 7150 一样高 ? 在 50 点的 h ¹ 吗？

英文摘要：

Formic acid（FA） dehydrogenation has attracted a lot of attentions since it is a convenient method for H_2 production. In this work, we designed a self-supporting fuel cell system, in which H_2 from FA is supplied into the fuel cell, and the exhaust heat from the fuel cell supported the FA dehydrogenation. In order to realize the system, we synthesized a highly active and selective homogeneous catalyst Ir Cp＊Cl_2 bpym for FA dehydrogenation. The turnover frequency（TOF） of the catalyst for FA dehydrogenation is as high as7150 h~（-1）at 50°C, and is up to 144,000 h~（-1）at 90°C. The catalyst also shows excellent catalytic stability for FA dehydrogenation after several cycles of test. The conversion ratio of FA can achieve 93.2%, and no carbon monoxide is detected in the evolved gas. Therefore, the evolved gas could be applied in the proton exchange membrane fuel cell（PEMFC） directly. This is a potential technology for hydrogen storage and generation. The power density of the PEMFC driven by the evolved gas could approximate to that using pure hydrogen.
