DESC:This application claims priority from provisional patent application number 202221072261 titled “Fuel Cell Electric Vessel (FCEV) for Inland Waterways” filed on 14-12-2022.

FIELD OF DISCLOSURE
[0001] The present invention relates to the field of maritime transportation, specifically to Fuel Cell Electric Vessels (FCEVs) tailored for inland waterways. Inland waterway transport is an essential component of sustainable and eco-friendly shipping, and the invention addresses challenges related to environmental impact and energy efficiency.

BACKGROUND OF THE DISCLOSURE
[0002] The development of a Fuel Cell Electric Vessel (FCEV) for inland waterways addresses several pressing needs in the maritime transportation sector.
[0003] A fuel cell is a type of device that uses electrochemical processes to directly transform the chemical energy of a fuel into electricity. In many aspects, a fuel cell is comparable to a battery, but it can deliver electrical energy for considerably longer periods of time. This is because a fuel cell is continually supplied with fuel and air (or oxygen) from an external source, but a battery only stores a finite amount of fuel material and oxidant, both of which decrease with usage.
[0004] There are various varieties of fuel cells available today, all of which perform similarly. One form of fuel cell is the phosphoric acid fuel cell. Phosphoric acid is used as an electrolyte in these fuel cells to channel H++. Temperatures in this range from 150°C to 200°C. Because phosphoric acid is non-conductive, electrons must pass through an external circuit to reach the cathode. The components of these cells corrode or oxidize over time due to the acidic nature of the electrolyte.
[0005] In general, in India, electric, solar-electric, and hybrid boats (electric and diesel) are being deployed as pseudo-green alternatives. Marine vessels are now powered by batteries (electric boats) in combination with solar panels and diesel generators (in hybrid mode). These vessels, however, cannot be called a genuine green option because to their poor durability.
[0006] Traditional vessels operating on inland waterways often rely on internal combustion engines powered by fossil fuels, contributing to air and water pollution, as well as greenhouse gas emissions.
[0007] There is a critical need for cleaner and more environmentally sustainable alternatives in maritime transportation to mitigate the ecological impact on inland waterway ecosystems.
[0008] The maritime industry is a significant contributor to greenhouse gas emissions, and the need to reduce carbon footprint is a global priority. An FCEV addresses this challenge by utilizing hydrogen fuel cells, providing an emission-free alternative to conventional vessels powered by fossil fuels.
[0009] Establishing extensive charging infrastructure for electric vessels on inland waterways poses logistical and economic challenges. The FCEV, powered by hydrogen fuel cells, reduces dependency on charging infrastructure by enabling quick refuelling, contributing to the feasibility of widespread adoption.
[0010] Inland waterway vessels often face varying operational requirements and cargo capacities, necessitating adaptable and versatile propulsion systems. The FCEV's modular design addresses this challenge, providing a scalable solution that can be customized to meet diverse operational conditions and cargo demands.
[0011] The maritime industry is under increasing pressure to adopt sustainable practices in line with global efforts to combat climate change. The FCEV serves as a sustainable and eco-friendly option, aligning with the growing demand for greener shipping practices and meeting regulatory requirements for emissions reduction.
[0012] Encouraging innovation in the maritime sector to adopt cleaner technologies may face resistance due to the traditional nature of the industry. The FCEV represents a technological leap, offering a compelling alternative that incentivizes the industry to embrace cleaner and more efficient solutions.
