Fuel Cell Electric Vehicles: Paving the Way to Commercial Success

Research focuses on boosting reliability, reducing costs, and designing infrastructure of the future.
As nations around the world pursue sustainable transportation solutions, the hydrogen fuel cell electric vehicle (FCEV) presents a promising opportunity for consumers and automakers alike. Automakers have made steady progress reducing the cost and increasing the performance of fuel cell propulsion systems, and most major vehicle manufacturers are geared to launch Fuel Cell Electric Vehicles (FCEVs ) in the U.S. market between 2015 and 2020.
Although fuel cell technologies are proven and effective, deployment challenges persist—particularly in terms of further reducing the cost and increasing the durability of fuel cells and getting sufficient infrastructure in place to support widespread consumer use. Researchers at the National Renewable Energy Laboratory (NREL) are collaborating with industry partners to remove some of these barriers.
In-line Diagnostics Help Reduce Cost, Improve Reliability
As the fuel cell manufacturing industry moves from small- to large-scale production, quality control is essential. Using NREL developed in-line diagnostics, manufacturers can more effectively identify defects in fuel cell components, leading to higher production volumes, improved reliability, and lower costs.

To help address this challenge, researchers use an NREL-developed optical reflectance system to identify defects in fuel cell membranes and apply active infrared imaging techniques to identify defects in electrode materials. These methods have been validated on a small-scale manufacturing line that can convey fuel cell component materials at speeds of 100 feet per minute.
Supporting a Hydrogen Infrastructure Rollout
NREL recently joined H2USA, a public-private partnership designed to promote the widespread adoption of FCEVs. This new partnership focuses on overcoming the hurdles associated with establishing a robust hydrogen infrastructure.
“NREL’s participation in this partnership builds on the lab’s extensive fuel cell and hydrogen technology validation and analysis experience,” said Jen Kurtz, manager of the hydrogen analysis group. “Our hydrogen systems analysis staff will collaborate with a team of analysts from other national labs, universities, and key stakeholder groups to evaluate infrastructure roll-out strategies and the business case for commercialization.”

This team will combine analytic capabilities refined over many years of systems analysis to understand the technical, market, and investment challenges associated with the transition to hydrogen, electric, and other alternative fuel vehicles. NREL will contribute a suite of modeling and analysis capabilities developed over the last decade in support of the U.S. Department of Energy’s Fuel Cell Technologies Office as well as technology validation; safety, codes, and standards; and market transformation expertise.
Renewable Hydrogen FCEVs
Because hydrogen can be made from a variety of domestic resources, FCEVs reduce our nation’s dependence on imported oil and diversify our transportation-related energy sources. While most hydrogen is currently produced from natural gas, NREL is investigating renewable hydrogen production technologies that tap into energy from the sun and wind.
“Here at NREL, we have four FCEVs on loan from Toyota that fill up on renewable hydrogen—wind turbines and solar arrays power electrolyzers that split water into hydrogen and oxygen,” Kurtz said. “We showcase these and other advanced vehicles at public events to raise awareness about the alternative transportation options available today and on the horizon.”

    Needed to put you one tiny remark to finally say thank you as before for all the gorgeous opinions you have featured on this page. It was really remarkably open-handed of you in giving without restraint all that many of us could have offered for sale for an e book to earn some money for their own end, most importantly seeing that you could have done it in the event you desired. These basics in addition acted as the easy way to recognize that other people online have the same keenness the same as my personal own to grasp way more on the subject of this issue. I am certain there are numerous more fun occasions up front for people who discover your blog post.

    I don’t know whether it’s just me or if everybody else encountering issues with your site.
    It looks like some of the written text within your posts are running off the screen. Can somebody else please
    provide feedback and let me know if this is happening
    to them as well? This could be a problem with my web browser because I’ve
    had this happen before. Thank you
