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.
AUTOMOTIVE FCEV SERVICE—WITH HYDROGEN SAFETY BUILT AROUND THE WORK
Automotive FCEV
Hydrogen Service Bays
Patent PendingMarathon Automotive FCEV Hydrogen Service Bays create a focused service environment for hydrogen-powered passenger vehicles. The bay coordinates hydrogen detection, upward airflow, containment, exhaust, alarms, interlocks and controls around the vehicle and the approved maintenance workflow.

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 Automotive Repair
FCEVs offer terrific benefits for consumers 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 dealership or repair facility for the growth of fuel cell vehicles.

Plan around the vehicle and the technician.
A dealership bay needs to fit the service operation as carefully as it fits the car. Start with the manufacturer’s procedures, the work you intend to perform, and the surrounding shop.
Read the buyer’s guide01
Vehicle & service envelope
Identify the models you support, vehicle dimensions, hydrogen storage locations, and the procedures your technicians will perform. Include open doors, raised hoods, lift travel, and component removal space.
02
Lift & shop coordination
Share lift information, column locations, aisle widths, existing utilities, and ceiling obstructions. The enclosure, capture hood, detection, and exhaust must be coordinated with those conditions.
03
Daily operating needs
Discuss customer vehicle flow, neighboring service stalls, tool access, and any planned changes to the service program. Define how the completed bay will fit your facility’s training and alarm-response procedures.
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.
Define the scope
Confirm the bay configuration, supplied components, engineering deliverables, and work assigned to each project partner.
