Concept Design of Intelligent BoP Based on Slot-/Rack-type Fuel Cell for Integrated Management of Hydrogen Fuel Cells

Due to the global warming problem, the importance of eco-friendly fuels that do not emit environmental pollutants is increasing as a substitute for existing energy sources. Hydrogen, an ecofriendly fuel, is an eco-friendly fuel with high energy density to weight and no emission of environmental pollutants, and its importance as a substitute for existing energy sources is increasing. In particular, hydrogen fuel cells can supply energy stably for a long time due to their high energy conversion efficiency, and water and heat produced as by-products can be used in other areas such as smart farms, so they have high added value other than electricity production. A hydrogen fuel cell consists of a fuel cell stack and BoP (Balance of Plant). A fuel cell stack is a device that produces electricity and heat by reacting hydrogen and oxygen. The BoP constitutes the power system package around the stack, which it performs thermal management, water management, and air supply management to efficiently produce electricity. In this paper, we design the concept of a low-cost slot/rack type fuel cell system for housing/building, which is easy to shape change based on intelligent BoP and tubular unit fuel cell, has high energy density per volume, and is convenient for troubleshooting.
