Unleashing

the Potential of

Fuel Cells

MORELife Project

The Durability Challenge

Proton exchange membrane (PEM) fuel cells are regarded as

a cornerstone of carbon-neutral mobility. Their high efficiency

and wide application range – from trucks to ships, trains, and

stationary power – make them attractive for future energy sys-

tems. Yet despite rapid progress, durability remains a barrier to

broad market acceptance. Users expect fuel cells to deliver a

service life comparable to conventional technologies, especial-

ly in heavy-duty commercial vehicles.

Failures associated with degradation are often only identi-

fied during costly, time-consuming lifetime tests or through

warranty cases. Start-up and shutdown cycles, dynamic load

changes, and starvation effects are particularly harmful. Ad-

dressing these issues requires a better understanding of how

operating strategies influence degradation – and how they can

be optimized to extend lifetime.

The MORELife Project

The MORELife project brings together strong partners from

industry and academia to address fuel cell durability. Fund-

ed by the Clean Hydrogen Joint Undertaking, it investigates

degradation mechanisms and develops strategies to improve

reliability, with the goal of enabling fuel cells to operate for up

to 30,000 hours in heavy-duty applications.

AVL contributes its diagnostics and validation expertise,

ensuring that new insights are translated into practical testing

and optimization approaches. At the core of AVL’s involvement

is AVL PUMA 2™ Fuel Cell Diagnostic Toolchain, a tool that

provides instant feedback on critical operating conditions

during commissioning, testing, and calibration. Stressors such

as start-up and shutdown cycles, dynamic operation, and

hydrogen and air starvation become visible. Combined with

the simulation tools AVL CAMEO™ and AVL CruiseM™, and

validated on Greenlight testbeds, the tool supports data-driven

optimization of operating strategies – finding the right balance

between efficiency, performance, and durability.

Proof in Practice: 50 % Less Degradation Stress

In application-relevant testing environments, the MORELife

consortium has shown how identical current cycles under

different conditions lead to differences in performance and

degradation. Optimized operating strategies, validated through

PUMA 2, reduced dynamic operation stress by up to 50 %.

These results highlight the value of a toolchain that combines

simulation, diagnostics, and real-world validation.

For industry and customers, MORELife delivers faster knowl-

edge transfer, reliable development decisions, and lower

testing costs. The insights gained support the design of

longer-lasting, more efficient fuel cells tailored to the demands

of heavy-duty mobility. 

Fuel cells promise high efficiency and

flexibility, but durability remains a major

challenge. The MORELife research project

brings together strong partners from industry

and academia – including AVL – to investigate

degradation and extend the lifetime of heavy-

duty fuel cells.
