Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This work aims to develop a comprehensive test plan for the quality assurance of PEM fuel cells during their production. The objective is to shorten the duration of the end-of-line test, which traditionally takes up to 24 hours, to a few minutes. This will facilitate mass production of fuel cells and enable the production of fuel cell vehicles on a larger scale.

• Fundamentals of Fuel Cell Technology
• Failure Mode and Effect Analysis (FMEA) for Fuel Cell Components
• Suitable Test Methods for Quality Assurance
• Measurement Uncertainties and their Impact on Manufacturing Tolerances
• Development of a Montage-Accompanying Test Plan

Zusammenfassung der Kapitel (Chapter Summaries)

• Chapter 1 provides a general introduction to the work, highlighting the importance of fuel cell technology and the need for efficient quality assurance during production.
• Chapter 2 delves into the fundamentals of fuel cell technology, covering the historical development, functioning, and components of fuel cells.
• Chapter 3 focuses on the Failure Mode and Effect Analysis (FMEA), which aims to identify potential failure modes in fuel cell components and their impact on the overall performance. This chapter also determines the necessary test characteristics to be evaluated during manufacturing.
• Chapter 4 presents a range of suitable test methods for the selected inspection characteristics. The choice of control methods considers the duration of the test and its suitability for mass production.
• Chapter 5 discusses measurement uncertainties and their impact on manufacturing tolerances. The chapter also explores the selection of appropriate measurement devices for the chosen test methods.
