Interconnector for High Temperature Fuel Cells

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes an improved interconnector for high temperature fuel cells, specifically designed to enhance the mechanical and electrical connection between the anode and the interconnector. The core idea is to electrically connect the side edges of the interconnector to the anode using a conductive medium, while the anode itself is mounted using spring elements. This structural advancement separates mechanical sealing and electrical contact functions, enhancing both long-term reliability and performance, especially amidst high temperatures and thermal cycling.

Use CasesContent extracted from patent full text and abstract with AI.

• Solid oxide fuel cell (SOFC) stacks used for stationary power generation
• High temperature fuel cell systems for backup or off-grid power solutions
• Industrial applications where efficient, durable high temperature fuel cells are required (e.g., combined heat and power plants)
• Transport applications (trains, ships, or buses) using SOFC technology
• Research and prototyping in advanced energy storage and conversion devices

BenefitsContent extracted from patent full text and abstract with AI.

• Improved long-term mechanical and electrical contact reliability under high temperature cycling
• Reduces the risk of failure due to thermal expansion mismatches and mechanical stresses
• Allows precise control of contact pressure via spring elements, helping to maintain proper sealing and conductivity
• De-couples sealing and electrical contact functions, minimizing performance loss over time
• Enables the use of cost-effective, temperature-resistant materials for both mechanical and electrical interfaces
• Potentially lowers maintenance requirements and extends the operational life of the fuel cell stack
