System consuming resources with holder for an exchangeable tank cartridge and method for continuous supply of these systems

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

This patent describes a system and method for continuously supplying operating fluids (such as methanol for fuel cells) from exchangeable tank cartridges, using an intermediate buffer container. The key innovation is the use of sensors and a buffer tank to allow uninterrupted operation during tank changes, preventing damage due to under-supply and ensuring that cartridges can be fully emptied before replacement. The system detects when a cartridge is empty and switches to the buffer, giving users time to replace cartridges without halting system operation or risking costly damage.

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

• Powering portable or stationary fuel cell systems (e.g., in off-grid or backup power applications) with methanol cartridges
• Continuous liquid supply in laboratory or industrial systems requiring seamless cartridge changes (e.g., chemical dosing, lubrication)
• Medical devices needing a disruption-free supply of fluids from exchangeable cartridges (e.g., continuous analyzers, infusion pumps)
• Food and beverage processing systems for adding additives or sterilizing agents without process interruptions
• Any system where hygienically sealed cartridges and uninterrupted liquid supply are critical

BenefitsContent extracted from patent full text and abstract with AI.

• Prevents costly damage to sensitive systems (like fuel cells) during cartridge changes by avoiding under-supply
• Allows full use of cartridge contents, reducing waste and costs
• Enables the user to swap cartridges without strict timing or system interruption, increasing convenience and system uptime
• Automated detection and signaling for cartridge replacement enhance reliability and ease of use
• Supports use with hazardous, hygienic, or sensitive liquids via sealed, easy-to-exchange cartridges
• Simple and cost-effective integration due to the system-centric sensor and buffer design

Patent Abstract

The method involves connecting a replacing tank cartridge (TP) to a buffer container (PB) by a supply line. A system extracts the operating medium from the buffer container and the tank cartridge during the operation. An operating medium reserve is provided over the buffer container after completely emptying the tank cartridge. A sensor (LS1) detects the changing of the tank cartridge by the change of air in the supply line liquid. Independent claims are also included for: (1) an operating fluid using system, particularly a fuel cell, with a buffer container; and (2) a tank cartridge with methanol for insertion in a fuel cell.
