PEM End-of-Line - Quality Assurance in the Production Process

Quality Assurance in the Production Process by an Evaluator End-of-Line
Example of an End-of-Line Evaluator to ensure quality in the production process

The series production of fuel cells or entire stacks is a highly complex process in which many work steps are interlinked. To ensure the desired product quality at the end of the production process, HORIBA FuelCon offers the Evaluator End-of-Line (EOL), a test system that can test fuel cells and stacks in a range of up to 250+ kW. It can be used to carry out fast-cycle automated quality tests for cells, MEAs and stacks.

The system is always designed according to customer specifications, whereby our cost-efficient design allows solutions to be realised for all requirements. These range from simple test stations with manual contacting or execution to automated systems that enable automatic contacting of the test object by means of a conveyor belt. To optimise the test time, important steps such as filling and emptying coolant and leakage tests can be carried out automatically.

The use of a trolley system also ensures that test specimens can be easily transported and handled without having to use additional equipment. Automated contacting systems and quick connections can also be integrated. During the testing process, fuel cells or stacks undergo predefined tests that are automatically analysed and displayed as ‘passed’ or ‘failed’ on a touch operator panel. Thanks to our open interface concept, the results are then transferred to the test bench database or, if required, to the customer database. The PEM end-of-line test bench can also be optionally equipped with additional features such as impedance analysis, barcode or DMC scanners.

To protect the test object and operator, the Evaluator EOL has a fail-safe PLC and a 3-stage alarm concept as standard, which fulfils the highest safety requirements. This ensures maximum performance under safe conditions that do not affect the test and production process.

Further detailed information can be found in the product brochure in the Evaluator End-of-Line section.
