阳极支撑蜂窝固体氧化物燃料电池可以实现高体积功率密度，提高高温下的热机械耐久性。到目前为止，我们已经展示了有希望的功率密度，并研究了流道结构对电池性能的影响，根据电池中氢分压分布在运行中。在本研究中，研究了不同氢气流量下电池的电流电压特性随多孔阳极衬底厚度的变化以及衬底内的强制对流，以阐明多孔阳极衬底内三维燃料传输对电池性能的影响。
An anode-supported honeycomb solid oxide fuel cell can achieve high volumetric power density and improve thermo-mechanical durability at high temperatures. We have so far shown the promising power densities and investigated the effect of flow channel configurations on the cell performance in terms of the hydrogen partial pressure distributions in the cell under operation. In the present study, current-voltage characteristics of the cell depending on thicknesses of the porous anode substrate and forced convection in the substrate are studied under different flow rates of fed hydrogen to clarify the effect of 3-dimensional fuel transport in the porous anode substrate on the cell performance.
