01 — How FCEVs Work
Pollution-Free Power
FCEVs use stacks of fuel cells that combine hydrogen with oxygen from the air to produce electricity, which then powers the vehicle's electric motors. The only byproduct is water — zero tailpipe emissions.
HEAVY-DUTY FCEV SERVICE—WITH HYDROGEN SAFETY BUILT AROUND THE WORK
Truck & Equipment
FCEV Hydrogen Service Bays
Patent PendingMarathon Truck & Equipment FCEV Hydrogen Service Bays create a focused service environment for heavy-duty hydrogen-powered vehicles. The bay coordinates hydrogen detection, upward airflow, containment, exhaust, alarms, interlocks and controls around the vehicle and the approved maintenance workflow. Engineered for roof- or chassis-mounted hydrogen storage.

Our Truck & Equipment FCEV Hydrogen Service Bays
Heavy trucks, forklifts, yard tugs, delivery vans — one bay platform engineered for the full mix of heavy-duty FCEVs.
Truck and Equipment Hydrogen Service Bays
A larger, taller service environment.
Built specifically for facilities that have a little more space and a broader range of vehicle types — including large equipment such as forklifts, tractors, and loaders. This model carries the same safety systems and features as our other models.
If your shop is strictly standard automotive, see our Automotive FCEV Hydrogen Service Bays. If you service very large FCEVs like buses, check out our Bus & Fleet FCEV Hydrogen Service Bays.

SCOPE OF SUPPLY
One Coordinated Project, Clearly Defined
Marathon engineers and manufactures the Hydrogen Service Bay system, coordinates the controls and ventilation package, and supports installation and commissioning according to the approved project scope. Facility work, utilities, permitting, fire protection, roof work and trade responsibilities are identified in the proposal so every party knows what is included before the project begins.
Need engineering? Marathon works with licensed engineering partners who can provide site surveys, mechanical, electrical and fire protection design, professionally stamped drawings, and third-party commissioning. Permitting remains the responsibility of the owner or their contractor.
COMMISSIONING & OPERATIONAL HANDOFF
Verify the Coordinated Safety Response
Commissioning verifies the installed system functions included in Marathon’s approved scope, including applicable detection, alarm, ventilation, interlock and control responses. Designated facility personnel receive an operational handoff covering the bay controls and normal system indications. Vehicle service procedures, emergency-response planning and technician qualification remain governed by the vehicle manufacturer, facility safety program and applicable authorities.
Code Compliance
Engineered for Applicable Codes and Local Review
Each Hydrogen Service Bay is engineered for the codes adopted for the project location and coordinated with the local Authority Having Jurisdiction (AHJ). Depending on the project scope, applicable requirements may include NFPA 2, NFPA 70, the International Fire Code, International Building Code, International Mechanical Code, and OSHA requirements. Final requirements are project- and jurisdiction-specific.
Understanding the Technology
Hydrogen Fuel Cell Repair for Trucks & Equipment
FCEVs offer terrific benefits for fleet operators and unique opportunities for service providers — when handled with the right infrastructure.
02 — The Service Process
Vehicle-Specific Workflows
Before service begins, technicians must follow the vehicle manufacturer’s procedures and the facility’s approved plan for shutdown, defueling or isolation, purging when required, and verification of a safe state. Marathon designs the service environment to support the approved workflow; the exact procedure remains vehicle- and project-specific.
03 — Why It's Different
Lighter-Than-Air Fuel
Unlike petroleum, hydrogen is lighter than air — if released, it rises and pools at the ceiling. The capture hood and enclosure direct released hydrogen to the exhaust, away from building lights and wiring.
The requirements for servicing hydrogen-powered FCEVs are highly specific. A dedicated H₂ service bay coordinates detection, airflow, alarms and interlocks as one engineered response to manage hydrogen risk during standard maintenance — preparing your fleet shop or repair facility for the growth of fuel cell vehicles.

Give large vehicles the working room they need.
Truck and equipment applications bring different dimensions, access requirements, and maintenance workflows. A bay layout should account for the actual work envelope before its dimensions are finalized.
Read the buyer’s guide01
Vehicle & equipment envelope
Provide the longest, widest, and tallest vehicle configurations, along with tank locations and expected component removal paths. Include raised cabs, service platforms, lifting equipment, and overhead access.
02
Structure & building interfaces
Review the building structure, clear height, support conditions, exhaust routing, and utility locations. Wall-mounted, freestanding, ceiling-hung, and retrofit approaches depend on the engineered application.
03
Shop workflow & future use
Identify adjacent work, equipment movement, access routes, and changes in the planned fleet. Reserve room for inspection and maintenance of the bay itself, including sensors, fans, and controls.
A Clear Project Scope
Know what happens around the bay.
A complete project connects the manufactured system to the building and the people using it. Confirm these responsibilities in your proposal and project documents.
