我们的第一个采用新型 Au-Pd-Pt 催化剂的燃料电池原型成功地展示了发电能力。为了减少铂族金属的用量并获得高CO耐受性，在多孔Au上应用了Pd和Pt的电化学原子层沉积。尝试5ML Pd和亚ML Pt沉积，并且电化学估计Pd和Pt的量分别为125μg/cm 2 和6μg/cm 2 。发电过程中未观察到 100 ppm CO 催化剂中毒。尽管峰值功率较差，约为 100 mW/cm 2 ，但第一个原型的结果令人满意。
Our first fuel cell prototype with a novel Au-Pd-Pt catalyst successfully demonstrated power generation. In order to reduce amount of platinum group metals and obtain high CO tolerance, electrochemical atomic layer depositions of Pd and Pt were applied on the porous Au. 5 ML Pd and sub-ML Pt deposition was attempted and amounts of Pd and Pt were electrochemically estimated to be 125 μg/cm 2 and 6 μg/cm 2, respectively. No catalyst poisoning to 100 ppm CO was observed during the power generation. Though the peak power was poor around 100 mW/cm 2, results were satisfying for the first prototype.
