Objectives
The R&D project PEMTASTIC aims to meet the key technical challenges to increase durability of membrane-electrode assembly (MEAs) for heavy-duty (HD) applications. These challenges are approached with a combination of model-based design and the development of a durable CCM using innovative materials tailored for heavy duty operation at high temperature (105°C).
The quantitative targets of PEMTASTIC are:

PEMTASTIC in numbers
- Call: HORIZON-JTI-CLEANH2-2022-1
- Type of Action: HORIZON-JU-RIA
- Acronym: PEMTASTIC
- Number: 101101433
- Duration: 36 months
- Start Date: 01 Feb 2023
Methodology
- Analysis of Truck mission profiles
- Identification of relevant fuel cell operation stressors
- Extensive degradation tests in differential cells
- Assisting physical-chemical material characterisation
- Micro- and mesoscale material modelling, 1D and 2D cell level modelling
- New materials: corrosion resistant supports, a novel catalyst deposition technique, and prototype ionomers for dry conditions
- Iterative adaptation based on experimental input
The final MEA and the concept of model-based development will be validated in a TRL4 short stack. Additional output will be advanced computational tools for modellling of fuel cell degradation for fast health assessment and performance forecasts.
Expertise
The consortium covers the full value chain of full stack / systems development (from material supplier to be integrated in FCEV OEMs.
The consortium is composed by solid, experienced and leading industrial organizations, owning substantial resources and networks. The consortium is also counting renowned universities, research institutes and sophisticated technology developers representing the various areas of expertise that contribute to the design and development of the proposed solution with all entities coming from countries all across Europe.
Structure
The work plan consists of 7 work packages which are linked as shown in Figure 18. Within WP1 the HD requirements will be analysed and PEMFC testing protocols will be defined along with the expected operation window of the MEA. In WP2 modification of materials and CCM design take place based on inputs from WP3 which focuses on modelling of degradation and simulation of end-of-life performance.
The respective goals of WP 4 and WP 5 are experimental durability testing and material characterization to understand and quantify degradation mechanisms and provide major input to the modelling work package. In WP6 all dissemination and exploitation tasks are consolidated, while project management activities are assigned to WP7.
