Flow distribution structure for fuel cell end plate, is formed by two or more adjacent plates including flow channel which meanders and has unequal branches

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

This invention relates to a flow distribution structure for the end plate of a fuel cell. It uses two or more adjacent thin plates with meandering flow channels that can cross planes and have unequal branch sizes. The design aims to optimize the way fluids (such as air or hydrogen) are distributed at the end of a fuel cell stack.

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

• Fuel cell vehicles that require uniform fuel and oxidant distribution
• Portable fuel cell systems for electronics and backup power
• Stationary fuel cell systems for residential or industrial power
• Improvement of manufacturing processes for thin, efficient fuel cell plates

BenefitsContent extracted from patent full text and abstract with AI.

• More uniform flow distribution in fuel cell stacks, improving efficiency and performance
• Reduced thickness, saving space and weight in fuel cell systems
• Enhanced manufacturability using stamping or impressing methods
• Potential for better thermal and chemical management in fuel cells due to optimized channel design

Patent Abstract

The flow distribution structure is formed by two or more adjacent plates. Total thickness is 1 mm or less. The continuous flow channel included, meanders in a single plane. Alternatively, at one or more points there is a cross-over into another plane. At branching locations, the cross section of one arm is reduced by comparison with the other arm. Arrangement of structural elements on one plate is congruent to that on the other plate. It is alternatively the negative of that on the other plate. The plates are stamped or impressed. Three or more adjacent plates define the structure. An independent claim is included for the corresponding method of manufacturing an end plate with a flow distribution structure.
