1. Key components of hydrogen fuel cells
In a hydrogen fuel cell, a hydrogen electrode acts as a catalyst to generate electrons and H+ protons. An electrolyte membrane conducts these protons, combining them with oxygen at an air electrode catalyst to form water. The efficiency of a process in which hydrogen and air produce electricity and water depends on the core material characteristics of the catalyst and electrolyte (collectively, the catalyst-coated membrane) and the gas diffusion layer materials (membrane electrode assembly that combines gas diffusion layer and catalyst coated membrane) controlling the gas supply and the efficient conduction of electricity.
2. Paris Agreement
This international accord on reducing greenhouse gas reductions entered into force on November 4, 2016, following its adoption by the parties to the UN Framework Convention on Climate Change. The 159 national and regional signatories account for about 86% of global greenhouse gas emissions. The main long-term goals of the Paris Agreement are to:
- Keep the increase in global average temperature to less than 2°C above levels before the Industrial Revolution and endeavor to limit the increase to 1.5°C.
- Peak greenhouse gas emissions as soon as possible, balancing emissions by sources and removals by sinks of greenhouse gases in the second half of the 21st century.
3. Sustainable Development Goals
United Nations Member States adopted Transforming our world: The 2030 Agenda for Sustainable Development in September 2015, including its 17 Sustainable Development Goals and 169 targets.
4. Range extender
The unit uses on-board hydrogen stored in tank(s) and fuel cells to charge the battery powering the motor of an electric vehicle while it is moving. Filling hydrogen is quicker than charging battery with improved ranges. A fuel cell vehicle is a vehicle that uses power that hydrogen fuel cell generates in accordance with accelerator operations to directly drive the motor.
5. Prepreg
The sheet of semi-cured intermediate molded product in which the carbon fiber is impregnated with a resin. The prepreg is laminated, thermoformed, and cured to create a composite.
