Title: Innovations of Sang-Joon John Lee
Introduction
Sang-Joon John Lee is a prominent inventor based in Stanford, CA (US). He has made significant contributions to the field of fuel cell technology, holding a total of 12 patents. His work focuses on creating efficient and cost-effective solutions for energy generation.
Latest Patents
One of his latest patents involves a simple, inexpensive, and highly efficient fuel cell. This innovative design features boundary structures made of a photo-sensitive material combined with selective patterning. The use of printed circuit board (PCB) fabrication techniques allows for the integration of boundary structures with two and three-dimensional electrical flow paths. The photo-sensitive material and PCB techniques are utilized to create micro-channel structures or micro stitch structures, which significantly reduce dead zones in the diffusion layer while minimizing fluid flow resistance. Notably, the fuel cell assembly is free of mechanical clamping elements. Instead, it employs adhesives that may be conductively contaminated and/or fiber-reinforced to provide mechanical and electrical connections, as well as sealing within the assembly. The backing layers are pre-fabricated with a natural bend, enhancing adhesive bonding and eliminating the need for massive support plates. Additionally, proton insulation between adjacent and electrically linked in-plane cell elements is achieved through structural insulation within the central membrane.
