When using hydrogen as a fuel, fuel cells emit only water. Fuel cell technology has matured enough that initial commercialization of fuel cell vehicles is already underway, but several technological barriers remain that impede commercialization and require research on materials, stack components, balance...
Fuel cells are usually named for their electrolytes. To date five different electrolyte materials have shown potential for commercial development. The five fuel cell types have different characteristics, which make each one suitable for some applications but not others. A short description of the ...
Scientists at Imperial College London have engineered a hydrogen fuel cell that utilizes iron rather than rare and expensive platinum, allowing better application of the technology.

"These materials establish a new high-water mark for usable hydrogen capacities in MOFs," the study states. Hydrogen fuel cells have long held promise as a no-emission power source forelectric cars. They have, however, taken a backseat to lithium ion batteries, which you'll find inside most...
Hydrogen fuel cells are more expensive than most other types of energy generation. Depending on the type of fuel cell, certain precious materials might be necessary for the fuel cell to function, which can drive up the production cost. There's also a lack of widespread infrastructure...
The start-up period is slightly longer for HT-PEMFC systems (5–15 min) due to the acid nature of polymeric membranes (polybenzimidazole—PBI) that requires materials suitable for operating under corrosive conditions, increasing the size of the fuel cell stack [145,146]. During the start-up ...
