DTU研发3D打印燃料电池，功率提升五倍

Researchers at the Technical University of Denmark (DTU) have achieved a monumental leap in energy technology, using advanced ceramic 3D printing to create a new hydrogen fuel cell design. The result? A staggering 500% increase in power-to-weight ratio. This breakthrough, published in April 2026, showcases how additive manufacturing is solving complex engineering challenges that were once deemed impossible.

丹麦技术大学（DTU）的研究人员在能源技术领域取得了巨大飞跃，他们利用先进的陶瓷3D打印技术创造出一种新型氢燃料电池设计。结果如何？功率重量比惊人地提升了500%。这项于2026年4月发表的突破性成果，展示了增材制造如何解决曾被认为不可能的复杂工程挑战。

The project, aptly named “Escape Flatland,” was led by Professor Vincenzo Esposito at DTU Energy. It moves away from the traditional planar, stacked design of Solid Oxide Fuel Cells (SOFCs). Instead, the team fabricated a single, unified, or monolithic, cell with a complex gyroid shape using Lithoz’s ceramic 3D printing technology (LCM).

这个恰如其分地命名为“逃离平面国”的项目，由DTU能源学院的Vincenzo Esposito教授领导。它摒弃了传统固体氧化物燃料电池（SOFC）的平面堆叠设计。相反，该团队利用Lithoz的陶瓷3D打印技术（LCM），制造出了一个具有复杂螺旋二十四面体形状的单一、统一的整体电池。

This architectural shift is the key to the performance gains. Professor Esposito explains it as a “real paradigm shift,” where the “combination of thin inner walls and elimination of interconnects and sealants results in a drastic loss of weight, reduced thermal mismatch and mechanical stress, all while significantly improving the utilization of the available volume.”

这种结构上的转变是性能提升的关键。Esposito教授将其解释为“一个真正的范式转变”，其中“超薄内壁的结合以及互连件和密封剂的消除，导致了重量的急剧减轻、热失配和机械应力的减少，同时显著提高了可用体积的利用率。”

Creating such an intricate, high-performance component required a specific toolset. The team used a Lithoz CeraFab printer and a specialized material: Yttria Fully Stabilized Zirconia (8YSZ). This ceramic is ideal for SOFCs due to its stability under extreme heat and stress.

制造如此复杂的高性能部件需要特定的工具集。该团队使用了Lithoz CeraFab打印机和一种特殊材料：钇完全稳定氧化锆（8YSZ）。这种陶瓷因其在极端高温和应力下的稳定性而成为SOFC的理想材料。

As Esposito noted, the “Elevated level of complexity” required for this concept was unachievable until this advanced 3D printing technology became available.

正如Esposito所指出的，这个概念所需的“高度复杂性”在这种先进的3D打印技术问世之前是无法实现的。

The numbers speak for themselves. The new monolithic design demonstrates a power-to-weight ratio approaching 1 W g−1, a fivefold increase over the 0.2 W g−1 typical of conventional planar SOFCs. By removing the traditional “Achilles heel” of interconnects and seals found in stacked designs, the team has unlocked a path to vastly better power density.

数据不言自明。新的整体设计展示了接近1 W g−1的功率重量比，是传统平面SOFC典型值0.2 W g−1的五倍。通过消除堆叠设计中传统的“阿喀琉斯之踵”——互连件和密封件，该团队开辟了一条通往更优功率密度的道路。

The researchers believe this type of high-efficiency SOFC is most promising for transport applications, where weight and power output are critical. However, the implications extend to industrial and residential energy systems, marking a significant milestone for clean energy technology. This innovation mirrors advances seen in other 3D printed thermal management systems, like next-generation heat exchangers.

研究人员认为，这种高效SOFC在运输应用中前景最为广阔，因为重量和功率输出至关重要。然而，其影响也延伸至工业和住宅能源系统，标志着清洁能源技术的一个重要里程碑。这项创新反映了其他3D打印热管理系统（如下一代热交换器）中看到的进步。
