New fuel cell technology can dramatically reduce costs


According to a recent study by scientists from the University of Delaware, scientists from the University of Delaware propose fuel cell-powered vehicles: The study was published in The essence of nanotechnology.

The study also highlights that a new fuel cell technology may be needed. For Yan, lead researcher, the approach is a new twist to traditional fuel cells, known as proton exchange membrane fuel cells or PEMFCs, which are based on expensive platinum-based catalysts. money. The team is pursuing an alternative technology, the hydroxide exchange membrane fuel cell (HEMFC), because of its inherent cost advantages. They cited the reason for this proposed conversion as a very simple arithmetic problem.

‘New fuel cell cars have low initial costs, long driving ranges and the ability to quickly recharge.’

“To make fuel cell cars a reality, the DOE (Department of Energy) has set a system cost target of $30 per kilowatt, or about $2,400 for a vehicle,” said Yan. each car. He added, “Currently, the cost for PEMFC is $52 per kilowatt, which is a huge improvement over where the technology started. But the catalyst only accounts for about $12 of that total, leaving the $40 on other ingredients. So even if we magically throw in, we can’t go all the way to the $30 goal with PEMFC.”

First, to become a commercial reality, fuel cell engines must cost as much as their gasoline counterparts, and switching from an acid base with PEMFC to a base with HEMFC would provide collateral benefits. in reducing all costs. “Then, if we agree that this is the best approach, we need to get everyone in the HEMFC research community involved. If we want to be successful, we have to work together.” Yan said. Ultimately, he says, just lower costs are not enough. “It doesn’t work to compare our results today with those of yesterday or the day before. To be commercially successful with HEMFC, we must match or beat PEMFC’s performance. It’s simple – we can’t be successful without equivalent performance,” he said.
