A compact bioethanol fuel processor with an all-in-one design of the auto-thermal reforming (ATR) and water-gas-shift (WGS) reactors was developed. The fuel processor has unique features, such as the annular-type reactors which are constructed by stacking disk-shaped Rh/Gd-doped-ceria-coated structured catalysts and insertion of an internal heat exchanger between the two reactors. This integration renders two distinctive temperature zones for the ATR and WGS reactions in the fuel processor with a total volume of 135 cm³. A hydrogen production rate of 30 sccm H₂/mL_reactor, equivalent to ca. 2.3 kW_e/L_reactor, and a CO level of 2.4–2.7 mol % (dry basis) were achieved under continuous long-term operation for 700 h. The as-produced gas is ready-to-use in high-temperature polymer electrolyte membrane fuel cells, and this combination can be a competitive solution for hydrogen mobility requiring high energy storage density.

紧凑型ATR–WGS集成的生物乙醇燃料处理器，适用于便携式和车载燃料电池应用

开发了一种紧凑型生物乙醇燃料处理器，该处理器具有自动热重整（ATR）和水煤气变换（WGS）反应器的一体化设计。燃料处理器具有独特的功能，例如环形反应器，其通过堆叠盘状Rh / Gd掺杂二氧化铈涂层的结构化催化剂并在两个反应器之间插入内部热交换器而构成。这种集成为燃料处理器中的ATR和WGS反应提供了两个独特的温度区，总体积为135 cm ³。氢气产生速率为30 sccm H ₂ / mL_反应器，约等于 2.3 kW _e / L_反应堆，在连续长期运行700小时后，CO水平达到2.4-2.7 mol％（干基）。所产生的气体可立即用于高温聚合物电解质膜燃料电池中，并且这种结合可以成为要求高储能密度的氢迁移率的竞争解决方案。
