Pyrazine-bridged Fe[M(C)(CN)4] complexes (M(C) = Pt(2+) and Pd(2+)) with 3D porous structures were utilized as the cathode of one-compartment H2O2 fuel cells, which operated in 0.3 M H2O2, using a nickel mesh as an anode. The power density of a H2O2 fuel cell using pyrazine-bridged Fe[Pt(CN)4] reached 4.2 mW cm(-2), which is the highest value reported for the one-compartment H2O2 fuel cells. On the other hand, H2O2 fuel cells using pyrazine-bridged M(N)[Pt(CN)4] (M(N) = Co(2+) and Mn(2+)) as the cathodes exhibited power densities lower than 0.01 mW cm(-2), indicating that Fe(2+) ions are indispensable to achieve the high power density.
具有三维多孔结构的吡嗪桥联Fe[M(C)(CN)₄]配合物（M(C) = Pt²⁺和Pd²⁺）被用作单室过氧化氢燃料电池的阴极，该电池在0.3 M过氧化氢中运行，使用镍网作为阳极。使用吡嗪桥联Fe[Pt(CN)₄]的过氧化氢燃料电池的功率密度达到4.2 mW cm⁻²，这是单室过氧化氢燃料电池报道的最高值。另一方面，使用吡嗪桥联M(N)[Pt(CN)₄]（M(N) = Co²⁺和Mn²⁺）作为阴极的过氧化氢燃料电池的功率密度低于0.01 mW cm⁻²，这表明Fe²⁺离子对于实现高功率密度是不可或缺的。
