Fuel Cells
.Ist das alles die gleiche seite?
Fuel cells convert hydrogen or other fuels directly into electricity through an electrochemical process, without combustion. The suppliers below manufacture and integrate fuel cell stacks and systems for stationary power, backup power, and mobile applications across European industry.
What Fuel Cells suppliers provide
Suppliers in this category cover fuel cell stacks, balance-of-plant components, and complete fuel cell systems for stationary power generation, backup power, and mobile or off-grid applications. Their core competence lies in matching fuel cell technology, whether PEM, solid oxide, or another type, to the required power output, fuel supply, and duty cycle. Many also provide system integration, hydrogen supply coordination, and maintenance services. Fuel cells are distinguished from battery storage by principle: they generate electricity from a continuously supplied fuel rather than storing and discharging pre-charged energy. In the pre-selection phase, compare which fuel cell technology and power range each supplier specialises in.
Relevant standards
Where fuel cell systems are supplied alongside hydrogen production equipment, ISO 22734 governs hydrogen electrolysers used to supply fuel. Associated electrical and switchgear equipment typically follows IEC 61439. Supplier quality management is typically certified to ISO 9001.
Frequently asked questions
How do fuel cells differ from battery storage?
Fuel cells generate electricity from a continuously supplied fuel, typically hydrogen, while batteries store and discharge pre-charged electrical energy. The two are often complementary in a wider energy system.
