This Small Business Innovation Research Phase I project will utilize direct-methane SOFCs to produce syngas by reacting methane with oxygen using electrochemical partial oxidation (EPOx). Syngas is a precursor for hydrogen and synthetic liquid chemicals/fuels including methanol and various hydrocarbons. Advantages are similar to ceramic membrane reactors: syngas without nitrogen dilution and reduced cost due to process intensification by combining the oxygen separation and partial oxidation steps. SOFCs have an added advantage - dual products: syngas and electricity - that can significantly improve economics. FCT recently demonstrated high-rate production of syngas (30 sccm/cm2) and high electrical power density (0.9 W/cm2) at 750°C using conventional Ni-YSZ anode-supported SOFCs. Stable SOFC electrical output was reported for up to 300 hours. This project will develop alternate support materials for SOFCs that facilitate direct stable operation in fuels such as natural gas and in the presence of sulfur. FCT proposes to implement its expertise in segmented in series SOFC design into for scaling up EPOx for commercial applications. A scale-up of EPOx generation to a small stack of approximately 100W and 4L/min of syngas will be performed.This project demonstrates a new technology with potentially major impact in the fuel cell and alternative fuels areas. It is well known that cost is the main barrier to commercial introduction of fuel cells and the acceptance of fuels such as hydrogen. By co-producing syngas/hydrogen and electricity, the method demonstrated here has the potential to decrease the cost of both. This will not be an incremental decrease in cost, as might be expected for an improvement of a technology, but a substantial decrease as a result of a completely new approach. This new technology has the potential to significantly impact commercialization of these technologies.

该小型企业创新研究第一阶段项目将利用直接甲烷SOFC，通过电化学部分氧化（EPOx）使甲烷与氧气反应来生产合成气。合成气是氢和合成液体化学品/燃料（包括甲醇和各种烃）的前体。其优点与陶瓷膜反应器相似：合成气无需氮气稀释，并且通过将氧气分离和部分氧化步骤相结合来强化工艺，从而降低成本。固体氧化物燃料电池有一个额外的优势-双产品：合成气和电力-可以显着提高经济性。FCT最近展示了使用常规Ni-YSZ阳极支撑的SOFC在750°C下高速率生产合成气（30 sccm/cm 2）和高电功率密度（0.9 W/cm 2）。据报道，SOFC电输出稳定长达300小时。该项目将开发SOFC的替代支持材料，以促进在天然气等燃料和硫存在下的直接稳定运行。FCT建议将其在串联SOFC设计方面的专业知识用于扩大EPOx的商业应用。将EPOx发电规模扩大到约100 W和4L/min合成气的小烟囱。该项目展示了一种新技术，在燃料电池和替代燃料领域具有潜在的重大影响。众所周知，成本是燃料电池商业化引入和接受诸如氢的燃料的主要障碍。通过共同生产合成气/氢气和电力，这里展示的方法有可能降低两者的成本。这不会是成本的逐步减少，因为可能会期望改进一项技术，而是由于一种全新的方法而大幅减少。这项新技术有可能对这些技术的商业化产生重大影响。
