Proton exchange membrane fuel cellspowered with both CO and H2

科学问题

摘要

The CO electrooxidation is long considered invincible in the proton exchange membrane fuel cell (PEMFC), where even a trace level of CO in H2 seriously poisons the anode catalysts and leads to huge performance decay. 

前言

The proton exchange membrane fuel cell (PEMFC) is one of the key enabling technologies for the transition to the upcoming hydrogen economy(1-9). However, PEMFCs have their Achilles’ heel, i.e., they are easily poisoned by carbon monoxide(10-12).

总结：本文的科学问题可以从摘要和前言中看出，内容还是非常简单的，本文的主要目的就是解决质子交换膜燃料电池中阳极材料（一般为铂金）的CO中毒问题，从而降低氢气成本。

话题：质子膜燃料电池（proton exchange membrane fuel cell, PEMFC）

支点

分析问题中出现的两个目标：

1. designing catalytic sites with reduced CO adsorption energy is highly desirable for tackling such a problem（即使只有10-1000ppm的迹量CO时Pt催化剂表面都有0.2v至0.5v的电压损耗，这意味着催化剂对CO的高吸附性）.

2.  specific catalytic sites capable of activating water at a sufficiently low potential is demanded.（水也是CO电化学氧化的反应物，所以电极需要由激活水分子的低电势活性位点）

如何证明这次试验做到了这两点：四大支点

1. Structural Characterization.结构表征

2. Electro-Catalysis Behavior in Acidic Electrolytes.在酸性电解质中的电催化行为

3. Catalytic Stability Evaluation 催化剂稳定性评价

4. Enhancement Mechanism 机理

拓展出的话题：

1. PEMFC
