本文报道了用于二氢（H2）氧化的电极，并且其基于来自柠檬酸杆菌属S-77的[NiFe]氢化酶（[NiFe]S77）。在氢半电池中，在50 mV下，它具有比Pt高637倍的质量活性（基于1 mg [NiFe]S77或Pt计算）。 [NiFe]S77电极在空气中也很稳定，与Pt不同，在一氧化碳中毒后可以100%恢复。在[NiFe]S77电极的表征之后，构建了包括[NiFe]S77阳极和Pt阴极的燃料电池，并且显示出具有比Pt可实现的功率密度更高的功率密度。
Reported herein is an electrode for dihydrogen (H2) oxidation, and it is based on [NiFe]Hydrogenase from Citrobacter sp. S-77 ([NiFe]S77). It has a 637 times higher mass activity than Pt (calculated based on 1 mg of [NiFe]S77 or Pt) at 50 mV in a hydrogen half-cell. The [NiFe]S77 electrode is also stable in air and, unlike Pt, can be recovered 100 % after poisoning by carbon monoxide. Following characterization of the [NiFe]S77 electrode, a fuel cell comprising a [NiFe]S77 anode and Pt cathode was constructed and shown to have a a higher power density than that achievable by Pt.
