 Considering a zero-emission fuel cell solution for your heavy-duty vehicles? If so, it’s essential to become familiar with this technology.

Fuel cells offer a unique value proposition for the electrification of heavy duty vehicles, including:

  • longer range than a battery only electric solution
  • heavier payload capacity, and
  • higher vehicle utilization, thanks to quick refueling.

More and more OEMs are looking at integrating fuel cells into their bus and truck programs. But many aren’t familiar with fuel cell technology, and don’t know where to start.

Choosing the right fuel cell technology partner will ensure your journey toward zero-emissions is a success. In this article, we share five recommendations when vetting your potential hydrogen fuel cell partner.

5 Considerations When Evaluating Fuel Cell Suppliers

1. Choose the right product for the application

Buses and trucks require long duty cycles. Therefore, fuel cell durability and performance over the long-term is key. A fuel cell system designed for a car will not meet the requirements of a heavy-duty truck. Simply put, heavy-duty vehicles need heavy-duty fuel cells. 

Today’s conventional diesel and gas vehicles follow this standard. Car engines are designed for cars, and heavy-duty truck engines are designed for heavy-duty trucks. Hydrogen fuel cell design must also be suited to the appropriate vehicle type.

Here are some parameters to consider when evaluating a heavy-duty fuel cell:

  • Select a fuel cell technology which enables fast on/off cycles like Proton Exchange Membrane (PEM) technology.
  • The material used in the fuel cell stack construction (e.g. plates) will impact its durability.
  • The fuel cell’s membrane electrode assembly (MEA) should be designed for a lifetime of 20,000 hours or above for heavy duty bus and truck applications.
  • The balance of plant components should be sized according to demanding duty cycle requirements.

2. Understand your fuel cell manufacturer’s technology road map and product life cycle cost

You’re about to embark on a long journey, so it’s best to think long term.  

Evaluating your potential supplier’s cost and technology road maps will ensure you’re able to meet your commercialization targets. Such road maps must be supported by evidence and key milestones. It should not only look at capital costs, but also maintenance costs, efficiency and durability. These have a key impact on the total cost of ownership.

It might not be in your best interest to choose a supplier with a lower-cost initial prototype for a small volume production series. In fact, your chosen heavy-duty fuel cell system should be manufactured on a large scale, and have the lowest life-cycle cost.

Finally, understanding the core competencies of your fuel cell supplier is also key. This will allow you to identify their strengths, including support processes, along with areas where you can add value to improve the product and reduce cost.

3. Review your fuel cell provider’s credentials and qualifications

It’s critical to evaluate your supplier’s brand reputation and impact. Check their financial stability and resources, including the balance sheet, people, quality control and global footprint.

Undertake proper due diligence. Evaluate whether your supplier is stable enough to continue doing business with you long into the future. Check if they have the resources to continue investing in, and improving on their technology.

Don’t forget about your supplier’s company culture and values. These are extremely important to consider when developing long lasting, valuable partnerships. They’re also essential for the successful commercialization of fuel cell vehicles as a whole.

4. Evaluate your supplier’s support and service capabilities

When purchasing a fuel cell system, you’ll be embarking on the integration of a new technology. Therefore, support with integration and field service is critical, not only at this early phase, but as the technology matures in your ecosystem.

Your supplier should offer a comprehensive training program to help your team become skilled in working with heavy-duty fuel cell vehicles. They should also have logistics in place to support you with parts on a timely basis when needed.

5. Identify the unique competitive advantages your provider can deliver

Evaluate potential suppliers based on the competitive advantages they can deliver to you.

For example, your supplier could deliver fuel cells that:

  • Use long lasting materials which deliver on product total life cycle cost targets
  • Have a flexible design, to ensure performance over a wide range operating conditions
  • Have a higher operating temperature, to minimize radiator size
  • Are capable of a “true” cold start from -25c, with no external energy required

Additional advantages could be that the supplier:

  • Has the ability to refurbish fuel cell stacks, re-using key parts and recycling others
  • Offers vertical integration from the MEA and bi-polar plate design to fuel cell system integration, to ensure they deliver on cost targets.


This is an exciting time, as you begin integrating a new zero-emission technology into your vehicles. Working with the right fuel cell provider will set you up for success, now and in the future.
