hydrogen fuel cell technology is still relatively expensive and not widely available for consumer use. While there have been advancements in hydrogen fuel cell technology, particularly in automotive applications, the costs associated with producing, storing, and utilizing hydrogen gas remain significant.
Typically, hydrogen fuel cells require a controlled and specialized infrastructure for storing and supplying hydrogen gas, as well as appropriate safety measures. Additionally, the systems often include various components such as a fuel cell stack, power conditioning equipment, and hydrogen storage tanks, which contribute to the overall cost.
While it is challenging to provide specific information about the current availability and prices of hydrogen fuel cells, it's important to note that they are generally considered more expensive compared to other power generation technologies such as batteries or internal combustion engines. However, ongoing research and development efforts are aimed at improving the efficiency and affordability of hydrogen fuel cells, which may lead to cost reductions in the future.
If you are interested in exploring hydrogen fuel cell options for generating 12 volts or 24 volts of current, I would recommend consulting with specialized companies, research institutions, or industry experts who can provide the most up-to-date information on available products and pricing.
