固体氧化物燃料电池不仅可以转化氢气，还可以转化二氧化碳，并且利用含有阳极的催化剂可以转化碳氢化合物燃料，从而可以使用木煤气。由于重整反应，木气中的碳氢化合物在一定程度上表现出直接转化为H2和CO的能力。因此，阳极处可用的 H2 和 CO 量取决于碳氢化合物的重整程度。为了说明不同的碳氢化合物含量以及由此产生的不同的 H2 和 CO 可用量对燃料利用率的影响（由于单独的重整率），提出了使用单电池试验装置对合成木气和不同的萘含量进行的测试。萘的转化不仅影响开路电压，而且影响运行期间的电池电压。因此，本文重点研究因萘和甲烷重整而产生的 H2 和 CO 的可用量变化而引起的电池电压的变化。将实验结果与理论平衡计算进行比较，以说明工艺参数对重整机理的动力学影响。
The ability of solid oxide fuel cells to convert not only H2but also CO and its utilization of a catalyst containing anode enabling the conversion of hydrocarbon fuels allows the use of wood gas. The hydrocarbons in the wood gas show the ability to be converted to H2and CO directly to a certain extent due to reforming reactions. Therefore the available amount of H2and CO at the anode is depending to what degree the hydrocarbons become reformed. In order to illustrate the impact of a varying hydrocarbon content and consequently of a varying available amount of H2and CO on the fuel utilization due to individual reforming rates, the performed tests with synthetic wood gas and varying naphthalene contents using a single-cell test rig are presented. The conversion of naphthalene impacts not only the open circuit voltage but also the cell voltage during operation. Therefore this paper focuses on the change of the cell voltage due to a changing available amount of H2and CO resulting from reforming of naphthalene and methane. The experimental results are compared with theoretical equilibrium calculations to illustrate the kinetic impact of the process parameters on the reforming mechanism.
