The hybrid fuel cell technology that powered this ship was produced by Proton Motor Fuel Cell GmbH. [173] In 2010, the MF Vågen was first produced, utilizing 12 kW fuel cells and 2- to 3-kilogram metal hydride hydrogen storage. It also utilizes 25 kWh lithium batteries and a 10 kW DC motor. [172] The Hornblower Hybrid debuted in 2012.
The fuel cell is powered by natural gas which a membrane breaks down into water, heat, carbon dioxide (CO 2), and hydrogen, with the latter passing through a second membrane where electricity is generated. [18] The micro combined heat and power fuel cell have approximately 85% total fuel efficiency. [13] [18] PEM fuel systems have an electric ...
Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower temperature/pressure ranges (50 to ...
Fuel-cell forklifts can work for a full 8-hour shift on a single tank of hydrogen, can be refueled in 3 minutes and have a lifetime of 8–10 years. Fuel cell-powered forklifts are often used in refrigerated warehouses as their performance is not degraded by lower temperatures. [75] In design the FC units are often made as drop-in replacements.

The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its British inventor, Francis Thomas Bacon, is one of the most developed fuel cell technologies. Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity.
The scaling up of electrode active areas also provided capabilities to develop higher power fuel cell stacks, each with 1500 Watts of power. [6] Metal hydride fuel cells have achieved a current density of 250 mA/cm 2. [12] To test durability, fuel cell stacks were successfully operated for more than 7000 hours. [12]
According to Canadian company Hydrogenics, in 2001, its 25 kW fuel cell weighed 290 kg and had an efficiency ranging between 38 and 45 per cent; however, by 2017, they were producing more powerful and compact fuel cells weighing 72 kg and with an efficiency between 48 and 55 per cent, a roughly five-fold increase in power density.

HT-PEM fuel cell was developed in 1995 for operation at higher cell temperatures aiming at lower sensitivity of PEM fuel cells regarding impurities. [3] Thus HT-PEM fuel cell technology is one of the youngest fuel cell types and HT-PEM fuel cell systems are produced since the 21st century by several companies.
