PEM燃料電池触媒および触媒コーティング膜（CCM）

プロトン交換膜（PEM）燃料電池は水素と酸素を水に変換し、それによってエネルギーを放出します。燃料電池の核は、両面が白金系触媒で覆われたポリマー電解質膜です（触媒層付き膜、CCM）。

PEM燃料電池、燃料電池オペレーション

PEM燃料電池は、蓄電、資材運搬車両、小型輸送・大型輸送等、さまざまな可動用途や定置用途に使用することができます。輸送部門では、燃料電池式電気自動車はバッテリー式電気自動車と部分的に競合しています。しかし、走行範囲がより広く給油回数がはるかに少ないという性質上、水素燃料電池自動車は長距離輸送や大型輸送に最適な技術です。

二酸化炭素排出量削減と気候中立社会を作るという使命に対して総力を上げて取組みが行われているため、広い範囲でPEM燃料電池の成長が見込まれています。これは、世界各地での燃料電池型電気自動車の導入と、そのコストの大幅な削減へとつながります。

Catalyst Coated Membranes (CCM) / Membrane Electrode Assembly (MEA) for Fuel Cells

Heraeus Precious Metals advanced CCM and MEA solutions are developed to meet the requirements of modern fuel cell stacks and systems. Whether deployed in commercial vehicles such as buses and trucks, marine vessels, or stationary power units, these solutions are engineered to deliver outstanding durability, high efficiency, and long service life. Combining the know-how in stack design and system integration by Freudenberg e-Power Systems with the in-depth expertise in precious metals catalysts by Heraeus Precious Metals, we offer high alingment with modern fuel cell operation, industrial production scales and precious metals services that enable large production volumes.

Catalyst Coated Membranes (CCM)

Catalyst Coated Membranes are critical components for fuel cell systems, as catalyst and catalyst layer design largely determine the overall system-level performance and durability. The quality of the CCM is pivotal for the efficiency, performance, and durability of fuel cells, enabling reduced operating costs over the whole lifespan of a stack.

With this partnership, Heraeus Precious Metals and Freudenberg e-Power Systems were able to create unique layer structures and catalyst particle size and distribution that enhance the performance in terms of both efficiency and durability. The performance and stability optimized CCMs thus lead to a long lifetime and lower total cost of ownership.

This results in a empirically proven CCM portfolio that addresses all aspects of commercial and technical competitiveness.

Membrane Electrode Assembly (MEA) for Fuel Cells

All high-volume catalyst-coated membrane (CCM) variants are also available as membrane electrode assembly (MEA) configurations utilizing the know-how of FEPS in sealing technologies and gas diffusion layers (GDL). The available MEA7 structure is a 7-layer structure, compried of CCMs laminated with advanced gas diffusion layers (GDLs) and customized frame. A tailored sealing solution integrates the entire cell architecture into a precisely engineered polymer frame, ensuring easy handling and efficient integration into fuel cell stacks. This sealing approach effectively eliminates gas crossover, contributing to extended operational lifetimes.

By adopting Heraeus Precious Metals’ high-volume MEA program, you gain access to the full performance advantages of the unique CCM technology while minimizing the cost for MEA manufacturing equipment. This strategy enables a reduction in the Total Cost of Ownership (TCO) for PEM fuel cells through three key avenues: a) utilization of high-performance, durability-enhanced catalysts; b) operational cost savings via the scalable production facility; and c) sustainable material management through closed-loop recycling, covering both production waste and end-of-life components.
