Hydrogen and Fuel Cells
NREL's Hydrogen and Fuel Cell efforts are quite extensive. Activities within the Chemistry and Nanoscience Center, funded by the Department of Energy's Fuel Cells Technology Office, focus on developing materials and components to help enable commercially competitive deployment of hydrogen (H2) and hydrogen-powered fuel cell devices in the market place.
Specific areas of active research include:
Fuel Cell R&D
Our fuel cell research and development (R&D) activities target improved cost, performance, and durability of fuel cell systems, with a focus on fuel cells for light-duty transportation (i.e., cars). Our current core and enabling competencies include alkaline membranes, extended surface electrocatalysts, and electrode integration. NREL serves as the Electrode Layer lead of the Fuel Cell Consortium for Performance and Durability (FC-PAD).
Testing and Fabrication
Our fuel cell and electrolysis testing capability is extensive and takes place within the Energy Systems Integration Facility NREL hosts advanced diagnostic test capabilities and the ability to test from small scale (single cm2 cells) to large scale (from 6-kilowatt stacks to 250-kilowatt systems). Additionally, we boast an advanced electrode fabrication capability, which includes multiple automated ultrasonic and electro-spray systems and in-line, roll-to-roll coating capabilities.
We perform R&D in the area of H2 production using multiple routes including photoelectrochemistry (see Solar Fuels), bio-hydrogen, and renewable electrolysis. Activities within the Chemistry and Nanoscience Center focus on photoelectrochemistry and electrolysis.
NREL has led a 14-member, cross-National Lab effort to highlight the broad value of renewable hydrogen within the energy system, and to prioritize the R&D required to effectively achieve a sustainable energy system.
Hydrogen Storage Characterization and Optimization Effort (HySCORE)
NREL has had a long history in the area of H2 storage. Our current activities include quantifying storage characteristics of novel materials and helping to achieve Energy Department storage targets. NREL is the laboratory lead in HySCORE, a collaboration between NREL, Pacific Northwest National Laboratory, and National Institute of Standards and Technology. The objective of HySCORE is to develop and enhance the Fuel Cell Technologies Office hydrogen storage core capabilities and validate claims, concepts, and theories of hydrogen storage materials.
NREL participates as one of four laboratories in the ElectroCat EMN.
NREL serves as the lead laboratory for the HydroGEN EMN.
We engage in R&D to accelerate the pace and reduce the cost of manufacturing and deploying H2 and fuel cell technologies. Our activities include developing and demonstrating in-line measurement and detection techniques that can be applied to roll-to-roll manufacturing processes, studying the impact of manufacturing defects on device performance and lifetime, and exploring process-performance relationships and scalability in the production of cell materials.
