Emerson’s hydrogen fuel cell solutions provide safety, reliability and efficiency for a more sustainable future
Hydrogen offers exponential growth for green mobility initiatives and will power hundreds of thousands of new commercial trucks and other vehicles in the next decade. Fuel cell system manufacturers face pressure to scale up production for this rising demand while also maximizing the safety, efficiency and reliability of their products. Emerson’s certified components, designed specifically for the hydrogen market, provide a single-source answer to these challenges.
Pressure fluctuations can rob hydrogen fuel cells of peak efficiency and performance. Emerson’s hydrogen regulators and valves maximize efficiency by controlling pressure and flow to ensure continuous hydrogen fuel supply, even in extreme operating temperatures. These low-maintenance solutions provide optimal energy output, meet the latest global standards, and help keep fleets on the road and out of the repair shop. With local manufacturing and support, Emerson is a partner you can rely on.

Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

Frequently Asked Questions about Hydrogen Fuel Cell Manufacturing
A fuel cell is a device that converts chemical energy into electricity. One of the most common types of fuel cells include PEM or Proton Exchange Membrane fuel cells which generates electricity via the hydrogen electrochemically reacting with oxygen while releasing only water (H2O) into the environment.
Hydrogen is an abundant element that, when harnessed for fuel cells, can provide green energy with zero carbon emissions.
Fuel cells can be used for an array of electricity needs, from power for on road vehicles including buses and trucks, to stationary power for buildings.
Emerson offers reliable products and solutions for your applications across the entire hydrogen fuel value chain
