Method for Manufacturing a High-Temperature Fuel Cell

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

This patent describes a method for the large-scale, industrial production of solid oxide high-temperature fuel cells using technology and equipment adapted from traditional paper manufacturing. The process involves creating a fibre-based supporting substrate mixed with ceramic and electrode materials, then forming and drying it using continuous papermaking techniques, followed by the automated application of electrode and electrolyte coatings. This approach enables fast, scalable fabrication of the core components of solid oxide fuel cells (SOFCs).

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

• Industrial-scale production of solid oxide fuel cells (SOFCs) for stationary and mobile power generation.
• Manufacture of SOFC components for integration into energy systems for hospitals, data centers, or grid support.
• Production of fuel cells for use in micro combined heat and power (CHP) units for residential or commercial buildings.
• Rapid prototyping and development of new SOFC designs for research institutions or industry.
• Enabling cost-effective fabrication of SOFCs for backup power in telecommunication infrastructure.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly increases the manufacturing speed and throughput compared to traditional ceramic processing (hundreds of meters per minute versus conventional batch rates).
• Substantially lowers production costs, making high-temperature fuel cells more affordable for widespread adoption.
• Enables mass production of SOFCs suitable for industrial and commercial applications, overcoming limitations of previous technology only fit for small quantities.
• Utilizes continuous processes and established papermaking machinery, reducing the need for expensive custom tooling.
• Improves consistency and uniformity of fuel cell substrates and coatings through automated, controlled processes.

Patent Abstract

The invention relates to a method for production of high-temperature fuel cells. This method is distinguished by the following steps: a) introduction of a filler as a supporting structure into an aqueous fibre suspension; b) addition of a retention means; c) application of this mixture from a) and b) to a sieve; d) removal of water from the suspension after a) and b); e) drying of the suspension after a) and b); f) compression of the substance obtained; g) application of a coating with electrode material and an electrolyte; h) application of the opposing electrode.
