PEM Cell Stack — 7-plate configuration, indicative visualisation

Cell-stack visualisation shown above is representative. Production geometry varies by customer specification. Detailed drawings under NDA.

Anchor Programme

Building electrolyzers with PETRONAS.

Limpahan executes the precision manufacturing layer of PETRONAS's hydrogen generation programme — compression plates, bipolar plates, current collectors, machined manifolds, and welded chassis — shipped from Kelantan with full traceability.

That work transformed Limpahan's positioning. The same floor that produces aerospace-grade precision components now produces the physical infrastructure of Malaysia's hydrogen supply chain.

Research Partner

UKM PEM fuel cell collaboration.

Limpahan collaborates with Universiti Kebangsaan Malaysia (UKM) on PEM fuel cell upgrades — translating laboratory-scale research into manufacturable geometry. Academic hydrogen expertise paired with an industrial floor capable of shipping the designs.

This is what Malaysian green-energy research needs to scale: not another whitepaper, but a shop floor able to take a UKM prototype and ship fifty of them.

HETR Alignment

Aligned with Malaysia's Hydrogen Economy Roadmap 2030.

Malaysia's national hydrogen ambition only becomes real when domestic manufacturers can build the hardware. Limpahan's role is clear: the precision manufacturing partner making hydrogen infrastructure inside Malaysia, for Malaysian demand, employing Malaysian machinists.

Green Hydrogen — 10-Year Plan

Six phases, from plate machining to global hydrogen export.

The strategic roadmap from current capability to becoming a regional hydrogen system exporter. Each phase compounds — today's plate machining is tomorrow's electrolyzer assembly is the next decade's hydrogen generation systems.

Phase 01
2022 – 2023
Plates Machining

First PEM electrolyzer plates machined on the Kelantan floor. Foundation of vertical integration.

Phase 02
2024 – 2025
Localization of Plates Coating

Domestic platinum coating capability — eliminates imported coating dependency for bipolar plates.

Phase 03
2024 – 2026
Electrolyzer Assembly (PEM & AEM)

Full stack assembly of both proton and anion exchange platforms.

Phase 04
2025 – 2027
Membrane Electrode Assembly

In-house MEA production — the catalytic core of every electrolyzer cell.

Phase 05
2028 – 2029
Hydrogen Generation — Local

Turn-key hydrogen generation systems shipped to Malaysian off-takers and industrial customers.

Phase 06
2029 – 2030
Hydrogen Generation — Global

Export-ready hydrogen generation systems — positioning Malaysia as a regional exporter.
